@Ads20000 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. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1766137 Title: [regression] Password accepted but login fails (blank purple screen and mouse pointer only) Status in gdm: Fix Released Status in Release Notes for Ubuntu: Fix Released Status in gdm3 package in Ubuntu: Fix Released Status in gnome-shell package in Ubuntu: Invalid Status in gdm3 source package in Bionic: Fix Committed Status in gnome-shell source package in Bionic: Invalid 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).
