Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in on the second attempt if you'd got your password wrong on the first
  attempt. All you'd see is a blank purple screen and mouse pointer
  only.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  WORKAROUND: After typing an incorrect password, click Cancel, then
  click your name, then enter your password again.

  ---

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous
  install of 18.04 (until Friday).

This bug affected me, but got past it by adding "nouveau.modeset=0"
after the text "quiet splash" in the bootparameters for Ubuntu in the
grub menu.

matt,

Please also note that a Core 2 Duo will suffer from bug 1727356 too.
Please apply the workaround from that bug.

[Daniel van Vugt]

matt,

The fix is in gdm3 version 3.28.2-0ubuntu1.1 and later.

You only have version 3.28.0-0ubuntu1 installed.

If you can't easily update then you might have more luck installing
version 18.04.1 directly (which might contain the fix if 18.04
didn't)...

you?version=18.04.1=amd64

[matt scott]

9-8-018 fresh install with updates .. some user switches work, some
don't logout is also crashing with irresponsive black screen. When the
user switch fails, the description is slightly different from above. If
the mouse pointer comes in at lower right, the user switch works. If it
comes in upper right, then the mouse fails, alt-F1 etc.  all do nothing,
and rather than blank purple screen, I have what appears to be a
successful login, but the system is completely non-responsive.

  in on the second attempt if you'd got your password wrong on the first
  attempt. All you'd see is a blank purple screen and mouse pointer
  only.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  WORKAROUND: After typing an incorrect password, click Cancel, then
  click your name, then enter your password again.

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous

[Brian Murray]

The policy for Stable Release Updates is to let them age a minimum of 7
days in the -proposed pocket before releasing them to the -updates
pocket. Reading the comments here I've noticed that the automated SRU
testing comment doesn't make any reference to that 7 day period nor does
it point to the wiki page that documents the aging period. I'll work
getting that fixed shortly.

Speaking with another SRU team member we've decided to waive the 7 day
period and will release the fixed version of gdm3 today.

[Heikki Moisander]

3.28.2-0ubuntu1.1 did work fine for login logout to another user (critical
in our environment). It has been few days since it was supposed to be
coming and I figured that it is safe now to start installing 18.04, but
fresh install 18.04 and I am still getting 3.28.0-Oubuntu1 - will not work.

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[OliFre]

@Ads2 Thanks for the link. Sadly, gdm3 is neither in the
autopkgtest-list, nor update-excuses, nor update-list, so it seems
things are stuck at an earlier stage and the documentation does not
clarify where to find out at which point help could be needed.

My intention was not to spam this report, but to find out where things are 
stuck (it's not obvious) and how to give support. 
It's also not about my personal (im)patience, but we have >200 desktops and 
>2000 Ubuntu containers and have had to stop the migration after the first 10 
desktops due to this bug (and three(!) other ones which all have been known 
*before* release and should either have been release blockers or been mentioned 
as "Known Issues" with the new LTS to prevent people from hopping onto the new 
supposedly-stable). For the other critical issues, QA apparently was even 
worse, since Debian and in one case also RHEL have already released fixes 
months or even a year ago, and there has been no reaction on Launchpad 
whatsoever yet. Since we are also still affected by critical bugs in 16.04 
which have been open since 16.04's release and could only be solved by PPA 
(broken OpenAFS), this makes me wonder whether Ubuntu still is a valid choice 
for institutional use, but this discussion certainly goes off topic here. 

Just let us know if there is something people could help with (testing
etc.). As it stands, the status is completely unclear apart from the
statement _to be patient_ - without indicating what the actual point is
where things are stuck.

Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in on the second attempt if you'd got your password wrong on the first
  attempt. All you'd see is a blank purple screen and mouse pointer
  only.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  WORKAROUND: After typing an incorrect password, click Cancel, then
  click your name, then enter your password again.

  ---

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous
  install of 18.04 (until Friday).

[Ads20000]

The conditions for the package to move to release are here:
https://wiki.ubuntu.com/ProposedMigration#Migrating_packages_from_-
proposed_to_release

It's possible that the update breaks something in release, though I'm
not sure what. It's also possible that we _just need to be more
patient_, it's only been a few days since it was put in proposed. I
don't see how spamming this bug is going to help the situation.

[HouseSessions]

Hi,

I'd like to test too - though being new here - can I (to avoid to switch
to proposed repo) just download and install the  AMD64 .deb files listed
under  proposed / 3.28.2-0ubuntu1.2  ?

thanks,
br, Koen

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[Jehandan Jeyaseelan]

Hi,

Tested the fix again - 3.28.2-0ubuntu1.2 on a fresh install of Ubuntu
18.04 LTS.

I went through all scenarios:

a) Login initially with incorrect password then correct password - Pass
b) Login by entering incorrect password multiple times then correct password - 
Pass
c) Created a second user (User B) then switched to that user entering correct 
password - Pass
d) Switched back to User A entering correct password - Pass
e) Switch between User A and B multiple times - Pass
e) Switched to User B entering incorrect password first then correct password - 
Pass
f) Switched to User A entering incorrect password first then correct password - 
Pass
g) Performed logout of User A, then unlocked User B with correct password - Pass
h) Performed logout of User B, then logged in to User A with correct password - 
Pass.

Fix now works perfectly. All good.

[OliFre]

Since it's still in proposed and a day is mostly over (and Europe is
asleep again) - could somebody outline / point me to the conditions for
a package to be moved from proposed to released?

This would be good to know to understand what is missing (and
potentially help?) instead of entering a lengthy discussion here, with
almost a 100 affected people and hence spamming lots of subscribers.

[Tuya]

I also have on this installation in addition to the bug described above
with the reboot... Can't reboot? Forced to do a hard reboot. Is it
related?

Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in on the second attempt if you'd got your password wrong on the first
  attempt. All you'd see is a blank purple screen and mouse pointer
  only.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  WORKAROUND: After typing an incorrect password, click Cancel, then
  click your name, then enter your password again.

  ---

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous
  install of 18.04 (until Friday).

only question is in which Ubuntu release. Presently you can see:

Wow! So once status is Fix Released that means, probably, usually,
hopefully, wait no more than 24 hours for the fix to hit your machine if

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[Daniel van Vugt]

Nobody can predict the future exactly, but given that the fix for 18.04
has now been verified I would *expect* it to be fully released later
today. Mainly waiting for Europe to wake up...

Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in on the second attempt if you'd got your password wrong on the first
  attempt. All you'd see is a blank purple screen and mouse pointer
  only.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.

  to do that. Those are also fixed.

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[tom]

Thanks Daniel!

So, my question is, how do I decipher (approximately) how many
hours/days away from release for 18.04 this fix is?

It's probably very obvious to old hands, but it's totally illegible to a
newb. Like, can I see what "branch" or "version" will have this fix? And
then, how do I see when that "branch" or "version" hits the normal
(18.04) distribution?

[Daniel van Vugt]

"Fix Released" will always occur for the development release first
(Ubuntu 18.10). Then existing stable versions after that.

You can see a fix for 18.04 is in proposed (not yet released) here:
  https://launchpad.net/ubuntu/+source/gdm3
So is only hours/days away from release.

Can someone take time to explain to a newb how/where to read in this bug
report when this fix will be pushed out?

Like, I see "Fix Released", but when does "sudo apt upgrade" see this
fix?

Tested multiple bad password followed with a good password. PASS
Tested switching from user A to user B; multiple bad password followed by good

Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in on the second attempt if you'd got your password wrong on the first
  attempt. All you'd see is a blank purple screen and mouse pointer
  only.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  WORKAROUND: After typing an incorrect password, click Cancel, then
  click your name, then enter your password again.

  ---

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous
  install of 18.04 (until Friday).

  - On Ubuntu accountservices only stores the language and not the
full locale as needed by LANG.
+ Add ubuntu_dont_set_language_env.patch:
  - Don't run the set_up_session_language() function, since it
overrides variable values set by ~/.pam_environment

Hi, in response to Marco's post #101,

I was wondering if a package will be released for bionic proposed so we
can test it out before it is released?

I can see that one is released for cosmic that is newer than the one for
bionic.

  it to the caller if it was returning an already-existing connection.

[Treviño]

So, the latest two commits of this branch:
 - 
https://gitlab.gnome.org/3v1n0/gdm/commits/client-connection-reference-fix-3-28

Should fix all the problems that I've tested so far.
Packaging will follow.

Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in on the second attempt if you'd got your password wrong on the first
  attempt. All you'd see is a blank purple screen and mouse pointer
  only.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

Re: [Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[Heikki Moisander]

Fresh install 18.04 gdm3 did succeed occasionally, but mostly froze
completely so that power button was only way out.
There was a fix that was available in proposed repository (or something)
that made things a bit different. Failure became a rule, but it was
possible to get back with ctrl+alt+F1/F2 (randomly pressing both)
Now this latest version is the first one that seems to work everytime. My
personal wish would be that please stop complicating the thing and put it
in production.

Switching users sometimes hangs since gnome shell 3.22. The bug exists
in debian stable. But it's not 100% reproducible.

[Daniel van Vugt]

Given that the same code has now been released in 18.10
(3.28.2-1ubuntu1), we should treat it as a new bug and maybe not
complicate the discussion here.

Can someone please log a bug against 18.10?

Hi,

In addition to my post #96 above, I downgraded gdm3 back to the release
version - 3.28.0-0ubuntu1 and am able to confirm that switching users
works perfectly between two users for me.

Therefore sounds like the fix for gdm3 - 3.28.2-0ubuntu1.1 - has
introduced further issues.

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[Jehandan Jeyaseelan]

Hi,

Confirm that there are switching user issues.

I logged in as user A, then created a second user - user B. I clicked on
Switch User and logged in successfully as User B.

I then proceeded to switch to User A by clicking on Switch User then
clicking on User A and entering the password. Resulted in being unable
to log back into User A.

Therefore fix still has issues and I agree with others here that it
cannot be released.

I think the fix should not be released until all issues associated with
it are resolved. If another bug is causing the switch user problem then
both bugs should be fixed before the gdm3 update with fixes is released.

Login functionality is critical to an operating system and should be
working perfectly. Having multiple users created in an Ubuntu 18.04 LTS
install is a very likely scenario.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  WORKAROUND: After typing an incorrect password, click Cancel, then
  click your name, then enter your password again.

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[Bodinux]

For information, I have had switching users issues since the fresh
install of 18.04 on top of not being able to login myself.

I let the gnome people continue to work on this issue and thank them for their 
work. In the meantime, my workaround is to turn back to lightdm which works 
very well for me (as it as done for some many years now):
-no login issues
-no multiple users switching issues
-automatic keyboard layout selection as per the user preference (we use 
different layout in my family)
-working on screen keyboard (displays other layout than qwerty).

I'll probably join ubuntu mainstream packages when these issues will be
solved.

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[KenWilson]

Regarding gdm3 3.28.2-0ubuntu1.1; regardless of what I do I cannot make
it work. Switching between users 100% of the time results in failure.

Here is what I have done:

Someone mentioned that after rebooting their system three times
(something like that) it started working albeit slow. I have rebooted my
system more than three times and it still doesn’t work.

Someone mentioned they switch users by locking the screen then from the
locked screen switch to a different user. What I have been doing is
clicking in the upper right corner, click on my name then click on
switch user. I have tried both methods with the same result, doesn’t
work. I can switch from ‘account A’ to ‘account B’ but I have not been
able to switch back to ‘account A’.

I have logged into ‘account A’ and then switched to ‘account B’. I can
logout of ‘account B’ and then login to ‘account B’ again, that works.
If I try to switch to ‘account A’ or logout of ‘account B’ and login to
‘account A’ I get locked out. I have the login screen for the two
accounts but cannot login to either. After a delay I am returned to the
login screen. At this point I did a CTRL-ALT-F4 to get a condole, which
worked. I logged into the console as ‘account A’, which worked. I then
did CTRL-ALT-F2 to return to windows and logged in to ‘account A’ which
sort of worked. I was logged in but things were not setup correct. For
instance I could not launch a terminal window; however, I could launch
Thunderbird. While in the console I did  (as someone suggested) ps aux |
grep , for the two accounts. I saved the output to a file
which I will attach (NOTE: for anonymity I will change the account names
to ‘account A’ and ‘account B’. Hopefully this will help someone better
understand the problem.

[Sergei]

I don't think you should release this because this produces more critical bug. 
This bug has some kind of workaround (cancel button), but I will have to 
disable updates if there is an upcoming update that will totally break an 
ability to switch users without any workaround. 
I believe I'm not the only one who has multiple users on my PC.

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[Treviño]

I think the issue is getting is there but maybe different from the one
originating this bug, so maybe to be handled in a different one...

So please, test this:

 1. Create another user
 2. Login with your user (or the other, as you wish)
 3. Lock the session -> Switch to other user from lockscreen
 4. Once back on GDM, select another user... Then you can login and redo what
said in 3. or just go back.
 5. From GDM, again try to unlock the 1st user, it fails.

Also `ps aux | grep ` shows running processes for
that session, while gdm seems to try to initialize a new one.

Anyway, while it's true this could be a regression of this change, I think it 
might be still better to release the version we have in proposed as this kind 
of issue can be handled in a different bug.
In any case I'm looking at it right now.

[Heikki Moisander]

I had similar experience yesterday after installing 3.28.2 and I reported
that it does not work. But after couple of boots I have been testing every
now and then maybe some 15 times and every time it has logged in - very
slowly but success anyway. To me that is quite clear that any kind of
success is better that need to boot every time. It is not about speed, but
we can not accept the situation user get frozen screen every time login in
after someone else. So if anything better is not available please take this
into production.

Re: [Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[KenWilson]

I installed package 3.28.2-0ubuntu1.1 and performed the testing again. I 
restricted testing to only switching between accounts. Same result, it 
did not work.

Listing... Done
gdm3/bionic-proposed,now 3.28.2-0ubuntu1.1 amd64 [installed]
gdm3/bionic 3.28.0-0ubuntu1 amd64

After installation I rebooted my system. I successfully logged into 
“account A”. I successfully switched to “account B”. I then tried to 
switch back to “account A” but was not successful. I am stuck at the 
login screen. I cannot login to either “account A” or “account B”. I had 
to reboot to gain control of my system.

  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in on the second attempt if you'd got your password wrong on the first
  attempt. All you'd see is a blank purple screen and mouse pointer
  only.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  WORKAROUND: After typing an incorrect password, click Cancel, then
  click your name, then enter your password again.

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[KenWilson]

All,
My testing indicates gdm3 3.28.0-0ubuntu1.1 fixes the incorrect password issue; 
however, it creates a new issue. As such I don’t think this update should be 
released. 

I installed gdm3 3.28.0-0ubuntu1.1 and rebooted my system (Ubuntu 18.04
LTS). Making sure I typed the password correct I was able to login to
each account on the system. I then logged out and performed the
following steps to ensure the password issue was resolved.

For two accounts I performed the following steps three times for each.
Each time succeeded.

1. I typed a bad password and pressed enter. I did this two times. Each 
time I was returned to the login screen and received a message the login didn’t 
work.
2. I then typed a correct password and successfully logged in. 
3. I then locked the screen and performed steps one and two and each time 
it worked as it should.
4. I then logged out of the account and performed steps one and two and 
each time it worked as it should. 
Based on this testing I would say recovering from a bad password is fixed.

The next test I performed was to login into one account and then switch
to the other account. I was able to successfully switch to the other
account. I then tried to switch back to the first account but I was
never able to successfully switch back. I tried it at least six times
and in no case did it work. It did not matter which account I logged
into first I was never able to switch to the other then switch back. In
each case when I switched the second time the system hung and I could
not find a way to recover. I tried CTRL+ALT+F2, CTRL+ALT+F1, CTRL+ALT+F2
but there was still unable to login. I was not able to login to any
account even when being extremely careful the password was correct.

I then reinstalled gdm3 3.28.0-0ubuntu1 and tried switching between
accounts. As long as I ensure I type the password correct I can switch
between accounts multiple times without issue. If I type an incorrect
password I can do CTR+ALT+F2, CTRL+ALT+F1, CTRL+ALT+F2 to recover.

With package gdm3 3.28.0-0ubuntu1.1 the only way I was able to regain
control (after trying to switch accounts a second time) was with a
system reboot. To me, having to reboot is a catastrophic failure and
therefor this package should not be released.

  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in on the second attempt if you'd got your password wrong on the first
  attempt. All you'd see is a blank purple screen and mouse pointer
  only.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*

  For this to work properly, we need to nullify the pointer we stored

  WORKAROUND: After typing an incorrect password, click Cancel, then
  click your name, then enter your password again.

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous
  install of 18.04 (until Friday).

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[Jehandan Jeyaseelan]

Hi I tested gdm3 - 3.28.2-0ubuntu1.1 on Ubuntu 18.04 LTS.

I ran the following tests:

a) Boot Ubuntu 18.04 LTS, attempt login with correct password - pass.
b) Log out and then log back in with correct password - pass.
c) Log out and then enter the wrong password a few times then enter the correct 
password press enter to login - pass.
d) Reboot Ubuntu 18.04 LTS, enter the wrong password a few times then enter the 
correct password, press enter to login - pass.
e) Login then allow the screen to blank, attempt unlock with correct password - 
pass.
f) Login then allow the screen to blank, attempt unlock with wrong password 
then enter correct password and press enter - pass.
g) Click on the lock button, attempt unlock with incorrect password a few times 
then enter correct password and press enter - pass.
h) Click on the lock button, attempt unlock with correct password - pass.

Fix therefore works now and appears to have no issues so far.

Ah, thanks for saying that since I was testing in my other machine and wasn't 
unable to reproduce this anymore...
My second user has no password set, but there's no much difference in terms of 
the issue.

Sorry I commented too quickly below after first tryout. After couple of
boots and tryouts it did finally succeed after longer wait time and now
after testing some 5 times I have managed to log with different user after
loging out. it is slow, but it will get there. So certainly I see good
progress, looks better now.

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[Łukasz Zemczak]

Hello Chris, or anyone else affected,

Accepted gdm3 into bionic-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/gdm3/3.28.2-0ubuntu1.1
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in

Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in on the second attempt if you'd got your password wrong on the first
  attempt. All you'd see is a blank purple screen and mouse pointer
  only.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  WORKAROUND: After typing an incorrect password, click Cancel, then
  click your name, then enter your password again.

  ---

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous
  install of 18.04 (until Friday).

[Heikki Moisander]

Mostly I don't understand this discussion and probably I should not take
part in it. There has been no progress visible to me. The bug I reported
was assigned as duplicate to this, so if this is now fixed, should I report
the bug again?

Anyhow it appears to me, that to ordinary users sharing the PC, 18.04 is
useless without changing back to lightdm (I hope that still works after
latest development.) In practice that is not an option to most basic users,
so going back to 16.04 or another distro is likely the choice. I am
confused after reading all this development discussion. I would assume this
is being fixed, but getting worried.

So, fix for this is actually in the upstream branch [1]. And that's
handled in gdm 3.28.1, so we should rebase on that in order to fix this.

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[calvin]

Sorry for my English, I'm French, this is a google translation of what I
mean.

@ Ads2 (ads2)
The problem is more complicated than that. When we enter our password and we 
validate it, we sometimes end up with a purple screen without cancel button 
visible, the only possibility is to do "crtl + Alt + F1 then crtl + alt + F2 to 
find GDM

Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in on the second attempt if you'd got your password wrong on the first
  attempt. All you'd see is a blank purple screen and mouse pointer
  only.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  WORKAROUND: After typing an incorrect password, click Cancel, then
  click your name, then enter your password again.

Oh, nothing else we can do short of ensuring others affected mark
themselves as affected so the bug heat is increased even further (which
demonstrates how serious the issue is without leaving impatient
comments!) :)

The fix was committed but 'verification-failed-bionic' which means that
it didn't work well enough. We have to wait for the developers to come
up with a better fix, and there's no ETA on that, unless you're a
developer yourself and know how to fix the issue we just have to wait.
It's not ideal but _there's nothing else we can do_, we just have to
click Cancel after entering an incorrect password and retrying for now

[dualshock3nerd]

I just found out yesterday that, if you enable auto-login, gdm never
hangs like this anymore.

This is kinda bad for security and debugging/testing but hopefully it
can still be of use to someone until this bug gets fixed.

Also this is not related to bad gnome extensions as, on my machine, gdm
still got stuck on a purple screen with no local extensions installed.

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[merinodanilo]

Hi,
I just fix the problem uninstalling the gnome extension "Workspace to Dock". 
Because i couldnt use my mouse and keyboard in the desktop i change to TTY with 
ctl+alt+F3 and remove that extension.

# rm -f -r $HOME/.local/share/gnome-shell/extensions/

or

# sudo rm -f -r /usr/local/share/gnome-shell/extensions/

Then

# gnome-shell --replace

After that didnt work so I reboot it, and it work.

I found this, because the problem appears to me after a fresh install
and installing some softwares, so i rebooted everytime i install mayor
software, or software that could modify the desktop. After a bunch I
install all the gnome extension i like and after a reboot the problem
appear.

The instructions for uninstalling an extension was found here:
http://bernaerts.dyndns.org/linux/76-gnome/345-gnome-shell-install-
remove-extension-command-line-script

Let me know if this helps you.

Regards

Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in if you'd got your password wrong.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  
  WORKAROUND: After typing an incorrect password, click Cancel, then click your 
name, then enter your password again.

  ---

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous
  install of 18.04 (until Friday).

It seems 3.28.0-0ubuntu1.1 isn't help to us. Now instead blank screen
with cursor we get hung after password entered and even Alt+Ctrl+F2 /
Alt+Ctrl+F1 can't help.

I am thinking that the fix has resulted in more issues than before
therefore I call it a blocker (due to increased issues). The fix needs
further testing and development.

Following on from post #62:

According to Bodinux's post and my testing, the login hang is
reproducible and I was able to replicate the issue every time I tested
it. It sounds like the login and logout process is working but not

Hmm, actually it is arguably worse with version 3.28.0-0ubuntu1.1

The problem with that version is that you can't log in more than once
without encountering a new login screen freeze, that is unlike this one.

Not sure if we want to continue with version 3.28.0-0ubuntu1.1 and deal
with that separately or call it a blocker.

Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in if you'd got your password wrong.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  
  WORKAROUND: After typing an incorrect password, click Cancel, then click your 
name, then enter your password again.

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous
  install of 18.04 (until Friday).

[Daniel van Vugt]

I have verified this bug is fixed on bionic using version
3.28.0-0ubuntu1.1

However I have also verified what the above comments allude to, in that
there are also other login bugs we will need to deal with later.

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[Jehandan Jeyaseelan]

I have tested the login process as follows:

a) Install gdm3 from bionic-proposed version 3.28.0-0ubuntu1.1 - in Ubuntu 
18.04 LTS and reboot.
b) When login screen appears, click on my username and enter incorrect password.
c) Enter correct password and press enter or click on sign in. Login successful.

However I have encountered the following issue:

a) Log out of Ubuntu 18.04 LTS.
b) Click on my username and enter my password correctly to login again and 
click on sign in or press enter.

The login prompt freezes, cannot click on cancel or the signin button.
When I click on the button to perform a restart or shutdown, it
indicates that I am still logged in therefore there appears to be an
issue logging out.

I also confirm that the issue as reported by Bodlinux in post #60 also
occurs exactly as described.

In this case clicking on the button to perform a restart or shutdown
indicates that I am logged in but haven't moved past the login screen to
the desktop so again an issue there.

I have only installed the gdm3 update from bionic-proposed, do we need
additional updates in order for the login system to be tested properly
or will the gdm3 update suffice?

[Bodinux]

Following #51 and #56 from Davide (tarski10)

I was able to reproduce. **.

gdm3/ 3.28.0-0-0ubuntu1.1
if I enter the wrong password once or twice and then I enter the correct 
password now I can access,
but if I enter the wrong password three times I return to the user choice 
screen and after clicking on my username ** and 
entering the correct password the screen freezes ** and 
nothing happens

Not sure what came out but this is out come of running journalctl right

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

Bodinux

after clicking your name, wait a while before entering the correct
password.

Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in if you'd got your password wrong.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  
  WORKAROUND: After typing an incorrect password, click Cancel, then click your 
name, then enter your password again.

  ---

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous
  install of 18.04 (until Friday).

Looks weird, can you attach the output of
  journalctl /usr/bin/gnome-shell

?

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous
  install of 18.04 (until Friday).

[Heikki Moisander]

I installed proposed updates. Now it freeze a bit earlier and even more
often. Login screen remain visible and no cursor movement while before in
looked like progressing with blank screen with cursor movement until final
freeze.

[Desktop-packages] [Bug 1766137] Re: [regression] Password accepted but login fails (blank purple screen and mouse pointer only)

[KenWilson]

Brian,
I attempted to install the proposed package: 3.28.0-0ubuntu1.1 but it failed. 
Initially I thought it installed correct but when switching users I got a 
notification of a timeout and a package not installed. In the process of 
looking at the notification it went away and I don't know how to get it back. I 
have included the dpkg log below. I have reverted back to the standard release 
and things are working as they were. 

NOTE: the install could be operator error.

I could not reproduce what Davide (tarski10) did.

I enter the wrong password three times I return to the user choice
screen and after clicking on my username and entering the correct
password I could successfully login.

Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in if you'd got your password wrong.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  
  WORKAROUND: After typing an incorrect password, click Cancel, then click your 
name, then enter your password again.

  ---

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous
  install of 18.04 (until Friday).

screen freezes and nothing happens.
I can still shutdown or restart.

Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in if you'd got your password wrong.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  
  WORKAROUND: After typing an incorrect password, click Cancel, then click your 
name, then enter your password again.

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous
  install of 18.04 (until Friday).

Bodinux,

It sounds like maybe you hit bug 1765261. That one will be fixed
separately in gnome-shell 3.28.2.

[Bodinux]

Tested this gdm3/3.28.0-0ubuntu1.1 from bionic-proposed.

Bad password entry followed by correct password entry works correctly.

I then tried to switch user, Bad password entry followed by correct password 
entry : screen with the grayed password box, nothing happening.
crtl-alt-f1, ctrl-alt-f2, log back to previous session ok
I then tried to switch user, correct password entry : screen with the grayed 
password box, nothing happening.
ctrl-alt-f1, ctrl-alt-f2, log back to previous session ok

(this might be another bug …?) but the test as I did failed.

gdm3 (3.28.0-0ubuntu2) cosmic; urgency=medium

  * debian/patches/0001-libgdm-Don-t-unref-a-connection-that-s-in-use.patch,
debian/patches/0002-libgdm-add-weak-pointer-for-connection-object.patch:
Cherry-pick two patches from the 3.28 branch. These fix a refcounting bug
in the GDM Client object, which had meant that the DBus connection was
being disposed too early in some cases, particularly when logging in after
a failed attempt. The symptom of that was that the system hung on a
"blank" screen. (LP: #1766137)

Bug description:
  [ Description ]

  Due to a refcounting bug, a GDBusConnection was getting disposed when
  it was still required. The symptom of this was that you couldn't log
  in if you'd got your password wrong.

  [ Test case ]

  1. Boot to GDM
  2. Click your username
  3. Type the wrong password a couple of times, pressing enter after each time
  4. Type the right password

  If the bug is happening, after 4. the system hangs at a blank screen
  with the mouse cursor. If you then switch to a VT or otherwise connect
  to the machine, you can examine the journal and you'll see a
  G_IS_DBUS_CONNECTION failure.

  [ Fix ]

  Marco and I worked upstream on this fix. We found out that there was a
  problem like this-

  The GdmClient has a shared GDBusConnection for its operations. The
  first time  someone calls for it, it is created and stored in the
  object's private structure. Subsequent calls return *a new reference*
  to this same object. It turned out that the asynchronous method to get
  the connection was accidentally unreferencing its object before giving
  it to the caller if it was returning an already-existing connection.

  For this to work properly, we need to nullify the pointer we stored
  when the connection goes away, so we know when to make a new one.
  There were some cases where we didn't add the weak references required
  to do that. Those are also fixed.

  [ Regression potential ]

  Now we share connections more than we did before. We also more
  carefully track when to clear our object. If we got this wrong, we
  might end up leaking the connection or dropping it in even more cases.

  [ Original report ]

  
  WORKAROUND: After typing an incorrect password, click Cancel, then click your 
name, then enter your password again.

  ---

  Trying to log into my session (Gnome, Xorg), if I enter the wrong
  password before entering it correctly, the session doesn't load and I
  get a purple screen, a mouse cursor, and an invisible but clickable
  menu in the top right. If I enter it correctly the first time, there
  is no problem.

  I've replicated this from a fresh boot, after logging out and after
  'sudo service gdm restart' from the Ctrl-Alt-F4 console.

  This is a fresh install, and didn't occur when I was using a previous
  install of 18.04 (until Friday).
