Thanks a lot for the details. I see several problems here:
1) At 15:00:15, there is a kernel error (RPM wakelock ref not held during HW access). So this may be related to the kernel upgrade. Adding a linux task. Can you check if it happens with stock kernel, not from HWE (linux- image-generic which is 4.15.0)? 2) At 18:16:33, gnome-flashback segfaults. Most probably the error was submitted to errors.ubuntu.com. However, to find it, it would be nice to know your whoopsie id. Can you please paste the output of this command: sudo cat /var/lib/whoopsie/whoopsie-id? Using this ID other people may see the crashes reported from your system (anyone will see the summary, developers will be able to see the details). If you worry about privacy, send me the output to [email protected]. 3) In several places, there is also this error: /usr/lib/gdm3/gdm-x-session[1894]: Fatal server error: /usr/lib/gdm3/gdm-x-session[1894]: (EE) EnterVT failed for screen 0 ... /usr/lib/gdm3/gdm-x-session[1894]: (EE) Please also check the log file at "/home/myuserid/.local/share/xorg/Xorg.0.log" for additional information. Can you please attach that file too? And I am also adding an xorg-server task. Note that I am the maintainer of gnome-flashback, so I will only be able to look at issue 2. I hope the maintainers of linux and xorg will be able to look at the other two issues. ** Also affects: xorg-server (Ubuntu) Importance: Undecided Status: New ** Also affects: linux-signed-hwe (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1842425 Title: No GUI with Gnome Flashback or Classic after apt dist-upgrade; Ubuntu on Wayland OK Status in gnome-flashback package in Ubuntu: New Status in linux-signed-hwe package in Ubuntu: New Status in xorg-server package in Ubuntu: New Bug description: Did apt dist-upgrade .

Other attempts: (1) Flashback: login transitions to purple background screen and no mouse. hitting alt-ctrl-F1 leads to an unlock screen with a next button. entering pw and clicking NEXT leads to animated circle wait icon. alt-ctrl-f2 leads to a TTY2 text mode console login screen. Login and sudo shutdown now -r (2) Gnome Classic: login transitions to a blank screen with the LCD displaying a "No video" message. alt-ctrl-f1 and unlocking there also transitions to a blank screen with the LCD displaying a "No video" message. alt-ctrl-f3 then Login and sudo shutdown now -r. (3) Ubuntu: same as with Gnome Classic.
