Network connection does not die. (It appeared to first time but I think that's just my ongoing random - and irrelevant here - avahi issues on this machine.)
But gnome-shell is *not* running after triggering the bug, so sudo killall on it just produces "gnome-shell: no process found". So that was the end of following the instructions above. :-) (Also this time round it did fail on the *first* logout too, so the fact of it not having done so the first couple of times may just have been a fluke. There are no other processes with gnome in the name running, nor is mutter. gdm3 and "gdm-session-worker [pam/gdm-autologin]" are apparently up. Using systemctl restart gdm3 seemed to work (I see a login screen) but doesn't really (it didn't autologin as expected per config, and attempting to log in just returns me to the login screen). I stopped gmd3 entirely (systemctl stop gdm3, then noticed "gdm-session- worker [pam/gdm-autologin]" was still running, though may have been a new instance as of the gmd3 restart (based on time started), so killed that manually), but then noticed there's a gnome-shell and other processes owned by me now running, but which I didn't get any sight of visually on the system's screen. After a while (while I was typing the above paragraph) they died on their own, and after *that*, a systemctl start gdm3 seems to have worked. As autologin is enabled, i got back into a new desktop session. This may point to it being related to console switching as suggested in the comments of the upstream bug. Stuff *is* happening (eg: gnome-shell *did* quit on logout, and it looks like I *did* login after the first gdm3 restart), but the console doesn't switch properly, so it appears dead. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1841915 Title: black screen, unresponsive, after logout from gnome To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1841915/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
