Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  == Test Case ==
  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

  == Regression Potential ==
  The option was accepted upstream, and nobody complained so far. So the 
regression potential should be low.

  This bug will cause static grey or black screen instead of opening
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and
  etc.

Hi,

Same thing is happening to me in Xubuntu 18.04 with xrdp. Is there any
fix for this? Thanks.

Which session do you try to use?

It is now May 31, 2016, it *still* doesn't work.  That's why I'm here.

Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  == Test Case ==
  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

  == Regression Potential ==
  The option was accepted upstream, and nobody complained so far. So the 
regression potential should be low.

  This bug will cause static grey or black screen instead of opening
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and
  etc.

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Reinier Post]

Christopher M. Penalver, the reported problem was that using remote
desktop to connect to an Ubuntu 14.04 with a gnome-session doesn't work.

It is now May 31, 2016, it *still* doesn't work.  That's why I'm here.

The problem description was since changed and a fix was developed for a later 
Ubuntu release.
While that is great, it does not fix the original problem.  The original 
problem won't have been fixed until a backport for 14.04 is available.  Now you 
say people reporting the original problem should do so in a separate bug 
report.  I'm happy do do that but I think it will be closed as a duplicate.

Will it?

Jonathan Laserson, as the scope of this report is already released, and
this report is closed, you don't have the same problem, but a different
one outside the scope of this report.

If you want your problem addressed, please file a new report (not

Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  == Test Case ==
  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

  == Regression Potential ==
  The option was accepted upstream, and nobody complained so far. So the 
regression potential should be low.

  This bug will cause static grey or black screen instead of opening
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and
  etc.

[Christopher M. Penalver]

adrhc, as this report is closed, it has nothing to do with your problem.

If you have an issue with RDP'ing to Ubuntu while using gnome-session-
flashback, you either haven't configured it properly (more likely as I
can use Windows RDC to connect to Vivid using gnome-session-flashback
just fine), or you have a corner case bug (not very likely).

Hence, please file a support request (not a bug report) via
https://answers.launchpad.net/ubuntu/+source/gnome-panel/+addquestion .
Please feel free to subscribe me to it.

[adrhc]

Thanks, but I said nothing about gnome-session-flashback.
I have no gnome-session-flashback and gnome-flashback package  installed (also 
I know nothing about them).
Instead I have the same result:
"4) What happens instead is it shows a gray static screen as per attached 
screenshot."
regardless of technical stuff behind ...

Guys I have:

me@me-desktop:~$ uname -a
Linux me-desktop 3.19.0-30-generic #34-Ubuntu SMP Fri Oct 2 22:08:41 UTC 2015 
x86_64 x86_64 x86_64 GNU/Linux
me@me-desktop:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:Ubuntu 15.04
Release:15.04
Codename:   vivid

just updated and still can't connect with RDC from win7 to Ubuntu. 
The RDC shows some logs then a gray screen then simply exits.
I noticed the "Fix Released" for Vivid but I don't know how to use it other 
than updating Ubuntu's packages.
Any hint ?

Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  == Test Case ==
  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

  == Regression Potential ==
  The option was accepted upstream, and nobody complained so far. So the 
regression potential should be low.

  This bug will cause static grey or black screen instead of opening
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and

Yes, it looks like you have the fixed version.

Please ask for support in an appropriate venue:

I haven't looked at xrdp ever since working on this bug, but IIRC it did 
still require a bit of configuration (see e.g. comment 58) and reading 
of scripts to see how things are put together.

 I cannot type 's' in gnome-terminal - it keeps on opening the
Applications menu.

This is probably bug 1440570 (the Trusty fix is waiting in the queue).

For the rest please open new bugs.

Chris, you might need to add:
export DESKTOP_SESSION=gnome-fallback
export XDG_CURRENT_DESKTOP=Unity
before gnome-session line:
gnome-session --session=gnome-flashback --disable-acceleration-check

Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  == Test Case ==
  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

  == Regression Potential ==
  The option was accepted upstream, and nobody complained so far. So the 
regression potential should be low.

  This bug will cause static grey or black screen instead of opening
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and
  etc.

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Chris Good]

Oops, I should have posted the comment first before adding an attachment. 
Here is the rest of comment #89:

I have attached the ~/.xsession-errors file.

The other problems are:

Many indicators do not work. eg nm-applet
I cannot type 's' in gnome-terminal - it keeps on opening the Applications menu.

Should I raise new bug(s) for these? This problem is sort of finished.
Should a new bug be for gnome-session or xrdp?

Thanks again.

[Chris Good]

Hi people,

Thanks very much for all the help.

I can run gnome-flashback in Ubuntu 14.04.2 LTS (up to date) using xrdp/vnc 
now, but it is not workable yet.
I'm using Remote Desktop from Windows 7 to connect to Ubuntu.

The major problem is that logging out doesn't work. The window changes to a 
blank purple screen and never closes.
All the processes still seem to be running.

Installed are:

gnome-session-flashback 1:3.8.0-1ubuntu12.2
gnome-session 3.9.90-0ubuntu12.1

~/.xsession :
gnome-session --session=gnome-flashback --disable-acceleration-check


I have attached the

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Chris Good]

Hi Alberts Muktupāvels,

Thanks for the suggestion. I tried it but it hasn't made any difference.
(I know the new environment values were used because I can see them in
the environment when running terminal in the gnome desktop). The
messages in .xsession-errors are in a different order but seem to be the
same.

I have attached the latest ~/.xsession-errors file.

Ah, right. Yes, this is a known problem with GNOME3 under NX3 and its

  gnome-session-flashback/Unity fails to start without hardware

Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  == Test Case ==
  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

  == Regression Potential ==
  The option was accepted upstream, and nobody complained so far. So the 
regression potential should be low.

  This bug will cause static grey or black screen instead of opening
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and
  etc.

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[martin lantz]

Hello Ryan and Alberts,

I figured out what was wrong.

Actually, gnome does start just fine by just running:
usr/bin/gnome-session --session=gnome-flashback --disable-acceleration-check

The screen resolution did not adjust to the monitor i am using and the
menu just happened to be off screen. The mate session seams to adjust
automatically.

(I did try to start using DESKTOP_SESSION=gnome-fallback and the log
was similar to what i have seen earlier)

Many thanks for all your help! It's really appreciated!

Kind regards,
Martin

Looks like the /etc/X11/Xsession wrapper is being used; it's trying to 
launch an Upstart session. In this case you need to export:

DESKTOP_SESSION=gnome-fallback
XDG_CURRENT_DESKTOP=Unity

in order for the upstart Xsession.d scripts to work properly.

[Michael Plotkin]

Just to reproduce the problem you are welcome to get it from
my ftp server: ftp://mplotkin.com
(login as anonymous).
Sorry, it can be slow - I am using a very old computer for ftp...
You need to install all three (appropriate of course) packages
on the server and just nxclient on the client.

Michael.

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[martin lantz]

Hello Ryan and Alberts,

I double-checked and I do have the mentioned versions of the relevant packages 
installed:
- gnome-session-bin 3.9.90-0ubuntu12.1
- libgnome-desktop-3-7 3.8.4-0ubuntu3.1

I logged into NX using gnome-terminal. From there I run:
/usr/bin/gnome-session --session=gnome-flashback --disable-acceleration-check 
 gnome-session.log.0

The desktop background image appears, but nothing else seems to work.

I uploaded gnome-session.log.0 here:
http://pastebin.com/tvVU2fMa

I also tried to log into NX using gnome-terminal and from there run:
export XDG_CURRENT_DESKTOP=Unity
export XDG_MENU_PREFIX=gnome-flashback-
/usr/bin/gnome-session --session=gnome-flashback --disable-acceleration-check 
 gnome-session.log.1

Still, only the desktop background image appears, but nothing else seems
to work.

I uploaded gnome-session.log.1 here:
http://pastebin.com/if7Cn0pF

What do you think I am doing wrong?

Kind regards,
Martin

Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  == Test Case ==
  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

  == Regression Potential ==
  The option was accepted upstream, and nobody complained so far. So the 
regression potential should be low.

  This bug will cause static grey or black screen instead of opening
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and
  etc.

Unity does not work under NX 3.5. These changes do not address that.

You should be seeing the classic GNOME desktop with panels on top and 
bottom. I've just tested the same gnome-session command you mentioned 
under x2goserver (based on NX 3.5) and it works.

Please double-check the versions of the relevant packages:
- gnome-session-bin 3.9.90-0ubuntu12.1
- libgnome-desktop-3-7 3.8.4-0ubuntu3.1

If you still have problems, please log into your NX with just xterm as 
the command (or gnome-terminal), run your gnome-session command in 
that terminal, and pastebin the output somewhere.

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[martin lantz]

Hello,

I am a bit confused on what to expect with the bug fixes that just have
been released.

I have NX version 3.5 installed on a Ubuntu 14.04 server. I have just
install the relevant version of the packages discussed above.

I can login successfully running the following command
/etc/X11/Xsession mate-session

But when I login using /usr/bin/gnome-session --session=gnome-flashback
--disable-acceleration-check the desktop appears but there is no menu
and no unity launcher.

Is this what I should expect or is there something else that I am is
missing?

Kind regards,
Martin

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Alberts Muktupāvels]

gnome-session was aborting if acceleration check failed. This bug was
about fixing it so it is possible to bypass this check. Bypassing this
check allows gnome-session to start.

You need to use session that does not require hardware acceleration, but
from you comment - you are using. As Ryan already told - you need to get
and paste log file to find why session does not fully start.

lightdm and other display manager are setting environment variables -
this might be your problem.

One thing you could try is to add this line before /usr/bin/gnome-session line:
export XDG_CURRENT_DESKTOP=Unity

Then you will need also this line:
export XDG_MENU_PREFIX=gnome-flashback-

Also you could add --debug to gnome-session line as it might show some
info why needed components are not started.

Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  == Test Case ==
  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

  == Regression Potential ==
  The option was accepted upstream, and nobody complained so far. So the 
regression potential should be low.

  This bug will cause static grey or black screen instead of opening
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and
  etc.

[Ryan Tandy]

Hi all,

The patches that were in my PPA (ppa:rtandy/flashback) are now in
trusty-proposed and utopic-proposed; so if you were using those
packages, please head over to bug 1416081, test the proposed packages,
and leave your feedback there.

If you had the PPA packages installed, please ensure you _downgrade_ to
the proposed packages as the version in -proposed is lower than what was
in the PPA. ppa-purge may help with that. (My bad; will choose ppa
versions more carefully next time.)

Thanks!

[Michael Plotkin]

I'm sorry - I don't understand this at all: local gnome-session always 
worked
all right without this fix in trusty-proposed, and the remote gnome-session
doesn't start at all with this fix in trusty-proposed but without other 
changes
from ppa:rtandy/flashback repository. At least this was my result...

 Not helpful? Without fix in trusty-proposed gnome-session will not start
 session... Segfault in libgnome-desktop is another bug/problem and is
 not directly related to this bug. And probably should be reported as
 separate/new bug.

Re: [Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Michael Plotkin]

Did reasonably extensive testing last night of the proposed fix for 
Trusty.
I believe that my results are very similar to Xavier: after I installed all
updates related to this bug from trusty-proposed repository (pre-released)
I couldn't start remote X2go session at all. In /var/log/messages I found
information about segfault in libgnome-desktop-3-7:

Apr  1 05:17:12 marina-net /usr/bin/x2goruncommand: launching session 
with Xsession-x2go mechanism, using STARTUP=gnome-session 
--session=gnome-flashback --disable-acceleration-c\
heck
Apr  1 05:17:20 marina-net kernel: [ 1747.973711] gnome-session[7806]: 
segfault at 18 ip 7fc4c3952196 sp 7fff7f38a820 error 4 in 
libgnome-desktop-3.so.7.0.0[7fc4c393+3\
1000]

  It appears that libgnome-desktop-3-7 wasn't update since July of 2014 
and its
version was 3.8.4-0ubuntu3. So I installed updates from 
ppa:rtandy/flashback
repository according to Xavier instructions, which includes updating
libgnome-desktop-3-7. After update the version of libgnome-desktop-3-7
became 3.8.4-0ubuntu4. Actually it updated 16 other packages as well at
that time. After this update everything began working very well.
  So my conclusion is that the fix in the trusty-proposed repository as 
it stands
there right now is not helpful at all, but the version in 
ppa:rtandy/flashback
repository works fine.

Thank you,
Michael.

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Alberts Muktupāvels]

So my conclusion is that the fix in the trusty-proposed repository as
it stands there right now is not helpful at all, but the version in
ppa:rtandy/flashback repository works fine.

Not helpful? Without fix in trusty-proposed gnome-session will not start
session... Segfault in libgnome-desktop is another bug/problem and is
not directly related to this bug. And probably should be reported as
separate/new bug.

Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

Not true. Your STARTUP above includes '--disable-acceleration-check' 
which was only added in the version currently in trusty-proposed.

Already fixed in vivid, and proposed patches for SRU. Any help getting

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Xavier]

Hi there:

I was also affected by this type of back when attemtping to connecto to
a Lubuntu 14.04 server with X2Go server there (and from a Ubuntu 14.04
with Unity and X2Go client, in case this matters). Things were working
as expected yesterday (no patches needed), when I was setting up the
whole server (X2Go, plus a few other server settings needed for
ISPConfig, Backintime, etc)

Since today I could not login thorugh X2Go using the same connetion to
LXDE that I was using yesterday (message shown today just after the
connection attempt: Unable to execute: startlxde), I found this bug
report,  and after enabling the extra repo trusty-proposed, I installed
the gnome-session-bin from there and gnome-session-flashback from
standard ubuntu repos. But it was not enough, it seems: I could see the
screen a little bit more evolved (blueish instead of fully black as
before), but  not enough. The errors shown server side at ~/.xsession-
x2go-errors were the ones shown in the attached document, corresponding
to the attempts to connect with a custom-desktop definition as:

gnome-session --session=gnome-flashback --disable-acceleration-check


After adding the repo ppa:rtandy/flashback, and upgrading packages
gnome-desktop3-data  libgnome-desktop-3-7, I was able to connect again
with X2Go and standard LXDE as a session, and no more errors shown in
the ~/.xsession-x2go-errors.

My commands in case anyones is looking for easy copypaste of
workaround:

sudo add-apt-repository ppa:rtandy/flashback
sudo apt-get update
sudo apt-get upgrade gnome-desktop3-data libgnome-desktop-3-7

I wonder if the addition of trusty-proposed was really necessary.

[Ryan Tandy]

Marking verified, based on my own testing and on Xavier's confirmation
that 'gnome-session --disable-acceleration-check' works for him in
trusty.

Xavier: right now 'gnome-session --disable-acceleration-check' is only
supported in trusty-proposed, as soon as it's released to -updates that
won't be needed any more.

Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  == Test Case ==
  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

  == Regression Potential ==
  The option was accepted upstream, and nobody complained so far. So the 
regression potential should be low.

  This bug will cause static grey or black screen instead of opening
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and
  etc.

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Dexuan Cui]

Hi, I'm using Ubuntu 14.04.2 LTS, is there a .deb package I can
directly dpkg -i?

Or, can I use apt-get install xxx  to get the updated correct binary?

Thanks a lot!

Dexuan: the updated package is in trusty-proposed repository
(https://wiki.ubuntu.com/Testing/EnableProposed describes how to enable
and use it).

When someone tests the fix and tags this bug as verification-done, the
fix will migrate to trusty-updates.

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Ryan Tandy]

I tried to verify this, but bug 1416081 blocks testing with
tightvncserver and xrdp as well as with x2goserver. Would anyone be
willing to upload the patches in that bug to -proposed as well? I will
fill in the SRU paperwork shortly. In the mean time,
ppa:rtandy/flashback contains the necessary patches for testing.

My testing steps:

- install gnome-session-flashback and tightvncserver,
- (trusty/utopic): install gnome-session-bin from -proposed,
- create ~/.vnc/xstartup with appropriate contents:

(vivid, session managed by gnome-session:)

export XDG_CURRENT_DESKTOP=GNOME-Flashback:Unity
export STARTUP=gnome-session --session=gnome-flashback-metacity 
--disable-acceleration-check
exec /etc/X11/Xsession

(vivid, session managed by upstart:)

export DESKTOP_SESSION=gnome-flashback-metacity
export XDG_CURRENT_DESKTOP=GNOME-Flashback:Unity
exec /etc/X11/Xsession gnome-session

(trusty/utopic, session managed by gnome-session:)

export STARTUP=gnome-session --session=gnome-flashback 
--disable-acceleration-check
exec /etc/X11/Xsession

(trusty/utopic, session managed by upstart:)

export DESKTOP_SESSION=gnome-fallback
export XDG_CURRENT_DESKTOP=Unity
exec /etc/X11/Xsession gnome-session

- chmod +x ~/.vnc/xstartup,
- run vncserver,
- from another host, run vncviewer.

The keyboard problem I mentioned earlier seems to be related to bug
568401 and bug 658723 (but not bug 112955 or bug 112309). Basically
Super modifier is always active when connected over VNC (or xrdp, as it
uses VNC behind the scenes). FreeNX/X2Go don't seem to have this
problem.

With regards to this bug specifically, AFAICT the gnome-session changes
in -proposed (supporting the --disable-acceleration-check switch, and
applying it to upstart-managed gnome-flashback sessions) are working,
but I'd love if a second person would confirm that!

Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  == Test Case ==
  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

  == Regression Potential ==
  The option was accepted upstream, and nobody complained so far. So the 
regression potential should be low.

  This bug will cause static grey or black screen instead of opening
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and
  etc.

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Alberts Muktupāvels]

In vivid gnome-session-flashback is created from gnome-flashback... So
in vivid gnome-panel has nothing to do with this bug.

Not sure if this is problem, but one thing could be missing --disable-
acceleration-check in /usr/lib/gnome-flashback/gnome-flashback-metacity.
This file is installed by gnome-session-flashback, so maybe gnome-
flashback needs little patch?

flashback/commit/?id=39dbfd09d4a7e16d5ca41319a62f173b8c79ca79

Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  == Test Case ==
  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

  == Regression Potential ==
  The option was accepted upstream, and nobody complained so far. So the 
regression potential should be low.

  This bug will cause static grey or black screen instead of opening
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and
  etc.

  3) What is expected to happen is when one installs xrdp on the host
  and attempts to use remmina or vinagre on a Ubuntu 14.04 client to RDP
  in, it works.

  4) What happens instead is it shows a gray static screen as per attached 
screenshot. This would appear an issue with gnome-session as per client log:

I have now uploaded gnome-flashback with that commit cherry-picked. We
are in freeze now, so that upload needs to be approved by the release
team first before landing to archive.

Christopher, why do you think this is a bug in gnome-panel? I see that
gnome-panel is not even started in your screenshot.

I don't have the environment needed for reproducing this so can't look
at it, but patches are welcome.

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Ryan Tandy]

Hi penalvch,

Whether or not this works with xrdp probably depends on how your session
is set up. I just tried installing gnome-session-flashback and xrdp on
the vivid daily CD; the default configuration does nothing, but the
following ~/.xsession:

env DESKTOP_SESSION=gnome-flashback-metacity XDG_CURRENT_DESKTOP
=GNOME-Flashback:Unity gnome-session --session=gnome-flashback
--disable-acceleration-check

does load the session. (but the keyboard layout seems wrong somehow...
:/)

If xrdp needs to be adjusted to set this up by default, or documented
somehow, maybe that should be a separate bug against xrdp.

Thanks for your work triaging and testing!

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Christopher M. Penalver]

Dmitry Shachnev, thanks for your quick response.

Christopher, why do you think this is a bug in gnome-panel?

I'll let you make the call on what is the root cause package.

Despite this, as per https://launchpad.net/ubuntu/+source/gnome-panel
gnome-session-flashback is provided by gnome-panel (not gnome-session),
which this report was supposed to be scoped to how xrdp'ing (among other
protocols mentioned) doesn't properly present a GUI when using gnome-
session-flashback (and Unity). What I can speak to is the issue that I
thought this bug report was scoped to still isn't addressed.

However, if you find that this report should be re-scoped, I'm happy to
file a new report on it.

I see that gnome-panel is not even started in your screenshot.

I'm not sure what you are talking about. To clarify what you are seeing,
it is my host computer (whose environment is irrelevant, could be
Windows, etc., but happens to be using Ubuntu) using a remote desktop
client (Remmina), remoting into a gnome-session-flashback environment
(the horizontal black/white lines, with a white diagonal line).

I don't have the environment needed for reproducing this so can't look
at it

Have you ever tried virtualization with Virtualbox? It's available via
the Ubuntu repositories, and works quite well. Also, one may setup a
temporary live environment as noted in
https://bugs.launchpad.net/ubuntu/+source/gnome-
session/+bug/1251281/comments/58 .

, but patches are welcome.

As I'm not a developer by profession, nor have that as a background,
this will unfortunately not be coming from me.

Ryan Tandy, thanks for testing to this issue, it is greatly appreciated.

Whether or not this works with xrdp probably depends on how your
session is set up.

Hmmm. All I did was a default install from http://cdimage.ubuntu.com
/daily-live/current/ , install xrdp and gnome-session-flashback, log
into gnome-session-flashback and attempt an RDP.

 I just tried installing gnome-session-flashback and xrdp on the vivid
daily CD; the default configuration does nothing, but the following
~/.xsession: env DESKTOP_SESSION=gnome-flashback-metacity
XDG_CURRENT_DESKTOP=GNOME-Flashback:Unity gnome-session --session
=gnome-flashback --disable-acceleration-check does load the session.
(but the keyboard layout seems wrong somehow... :/)

Unfortunately, I'm not following you here. Could you please provide this
information in a keyboard click-for-click fashion?

As well, just to clarify, making the modifications you advised above
allows you to see an actual desktop GUI (icons, windows, etc.)?

If xrdp needs to be adjusted to set this up by default, or documented
somehow, maybe that should be a separate bug against xrdp.

I already started a support article on xrdp at
https://help.ubuntu.com/community/xrdp . Once I can reproduce your
results, I'm happy to put it up there in a keyboard click-for-click
fashion.

  gnome-session-flashback/Unity fails to start without hardware

Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  == Test Case ==
  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

  == Regression Potential ==
  The option was accepted upstream, and nobody complained so far. So the 
regression potential should be low.

  This bug will cause static grey or black screen instead of opening
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and

Dmitry Shachnev, I still have the issue where when one uses xrdp with
gnome-session-flashback in Vivid, it shows a borked screen as noted in

[Michael DePaulo]

@plotkin I do not know because I no longer have a copy of NX 3 that I
can install, and NoMachine removed it from their site.

I would look for a config file under /etc/ where you can define what the
GNOME session command is. If that doesn't work, look for an NX 3 script
under /usr/ (I am not sure where they store their files) that defines
what command to call, and edit it. (Assuming their license permits you
to edit said scripts.)

[Rolf Leggewie]

Ryan, thank you for providing that patch. I hope the sponsors team will
have team to review and upload it soon.

A minor yet important nitpick for trusty is that you should target
trusty-proposed in the changelog, not trusty itself.  But first, we need
to get that fix into vivid anyhow.

** Changed in: gnome-session (Ubuntu Vivid)
Milestone: None = ubuntu-15.03

** Changed in: gnome-session (Ubuntu Trusty)
Milestone: None = ubuntu-14.04.3

Re: [Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Michael Plotkin]

Thank you Michael, very much, but in a sense my question was
whether there is (there would be) a way to have this option -
--disable-acceleration-check always (by default), so my users
wouldn't need to change their existing setups of many NX client
sessions that they already have.

  Also NX has an option to start different sessions (Desktops as they
call it)  including Gnome or, alternatively, run any specified command.
If I specify to run gnome-session command - it doesn't work correctly
at all. I don't know exactly how they lunch gnome-session when I select
GNOME Desktop in their configuration menu (there are no sources
as you know) and I didn't spend much time yet investigating this.

Michael.

 You may have to put that line in a script, and tell NX 3  to launch that
 script. That's what you will have to do with X2Go at least.

 I wrote the logic in X2Go for --session=gnome-flashback. I still need
 to write the logic in X2Go for --disable-acceleration-check. Once I
 do, X2Go users can simply select GNOME as their session.

[Michael DePaulo]

@plotkin it should work as long as you tell NX 3 to run the command:
gnome-session --session=gnome-flashback --disable-acceleration-check
(Not tested)

You may have to put that line in a script, and tell NX 3  to launch that
script. That's what you will have to do with X2Go at least.

I wrote the logic in X2Go for --session=gnome-flashback. I still need
to write the logic in X2Go for --disable-acceleration-check. Once I
do, X2Go users can simply select GNOME as their session.

[Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Ryan Tandy]

I am happily running GNOME Flashback with the FreeNX server, and nx-libs
from the X2Go stable PPA, on multiple Trusty terminal servers and it has
been quite stable. The gnome-session --disable-acceleration-check option
is needed, and also bug 1416081 has to be fixed to stop unity-settings-
daemon from crashing. I have uploaded all the necessary patches to
ppa:rtandy/flashback and attached them to these bugs. In the PPA I also
patched gnome-session-flashback to use --disable-acceleration-check, but
it's not really necessary -- just for symmetry :).

Attached is the FreeNX config file I use. Note it relies on the Upstart
session job to pass --disable-acceleration-check to gnome-session. For
X2Go, /usr/bin/x2goruncommand has to be adjusted similarly; I will
follow up to their tracker (http://bugs.x2go.org/cgi-
bin/bugreport.cgi?bug=774) soon.

I hope these patches can be considered for vivid, and maybe for
trusty/utopic SRU as well. Thanks for reading!

Re: [Desktop-packages] [Bug 1251281] Re: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

[Michael Plotkin]

Thank you Ryan for helping to resolve this problem. I've been waiting
anxiously for this problem being fixed because it's the main reason I
cannot start using 14.04 (and have to use 12.04) on a lot of systems.

I have a question - do you see any problems using original NX software
with this solution. For mostly historical reasons I've been using original
NX software (NX 3 from NoMachine) and have their client software
installed on quite a few computers.

Thank you,
Michael.

 I am happily running GNOME Flashback with the FreeNX server, and nx-libs
 from the X2Go stable PPA, on multiple Trusty terminal servers and it has
 been quite stable. The gnome-session --disable-acceleration-check option
 is needed, and also bug 1416081 has to be fixed to stop unity-settings-
 daemon from crashing. I have uploaded all the necessary patches to
 ppa:rtandy/flashback and attached them to these bugs. In the PPA I also
 patched gnome-session-flashback to use --disable-acceleration-check, but
 it's not really necessary -- just for symmetry :).

 Attached is the FreeNX config file I use. Note it relies on the Upstart
 session job to pass --disable-acceleration-check to gnome-session. For
 X2Go, /usr/bin/x2goruncommand has to be adjusted similarly; I will
 follow up to their tracker (http://bugs.x2go.org/cgi-
 bin/bugreport.cgi?bug=774) soon.

 I hope these patches can be considered for vivid, and maybe for
 trusty/utopic SRU as well. Thanks for reading!

[James David Smith]

I'm a very newbie Linux guy, but have been using Ubuntu through XRDP for
a year or so now (accessed via windows remote desktop from a PC).
Unfortunately since I upgraded Ubuntu to 14, it's stopped working. I
installed XFCE, but that has caused other problems. I'd really like to
use the standard Unity desktop. I hope that the discussions above come
to a point where this is fixed.

@tomdeering7,
PPA was not tested (at least by me) with 14.10 and probably won't be.
Currently I have no specific plans for supporting non-LTS releases, but I will 
review the situation when 15.04 will reach RC state.

[tdeering]

Eugene's PPA doesn't seem to fix this for me on 14.10.  If I log in with
NX and gnome-session --session=gnome-flashback, I still get a black
screen. Am I missing something? Or were the fixes only intended to work
with 14.04?

  3) What is expected to happen is when one installs xrdp on the host
  and attempts to use remmina or vinagre on a Ubuntu 14.04 client to RDP
  in, it works.

  4) What happens instead is it shows a gray static screen as per attached 
screenshot. This would appear an issue with gnome-session as per client log:
