OK, so I kind of messed up in that I did at some point get things working again, but didn't realize it because while I was experimenting and testing/trying to figure things out, I run a dual monitor setup (unequal sizes) and wound up swapping the monitor cable outputs so that when things started working again, the GUI login prompt was on a different monitor (shared with another system) which was selected to a different video input source. This swap was because the POST and text boot sequence was showing on the wrong monitor on startup, and (once working) the GUI login prompt is on the other monitor, and it still shows on that monitor despite selecting which monitor should be primary in desktop settings once logged in.
Honestly that's a real problem that should be fixed: the primary monitor which is being used for the text boot sequence is the one that should be displaying the GUI login prompt, not whatever criteria (largest screen resolution?) is currently being used. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/2090805 Title: gdm blank screen Status in xorg package in Ubuntu: New Bug description: After applying updates, Ubuntu 22.04 suggested rebooting the system. After rebooting the system, the GUI doesn't come up. It also seems to have changed grub defaults so that the grub menu no longer displays for a countdown of 3 seconds. During the first reboot after the update, a whole bunch of errors in red flashed by as part of the boot sequence but I wasn't able to capture them. That led to a non-responsive black screen with no cursor. Then I tried a couple of more reboots, but while I didn't see any red text, the system still didn't put up a GUI. I tried a few things that didn't work. I then tried to do a do- release-upgrade to Ubuntu 24.04 that I had been putting of because I couldn't afford the risk of downtime if the upgrade went badly in case it fixed whatever config snafu the first package-level upgrade screwed up. I also tried to do a package reinstall of the ubuntu-desktop, gdm, and gnome packages and none of that work, although I did get a cursor on a black screen at one point, so I think the compositor is working, but the display manager isn't working. I can run commands on the Ctl-Alt-F2 virtual console, which is how I initiated this bug report, but that's it. As far as I know, I'm running gnome with the Wayland compositor. There were a bunch of apparmor messages and warnings at one point, so I'm not sure if that could be the problem.
