Thank you, I was exactly hoping for a guidance on how to debug this issue further.
The crash happened today 10:55:00; please find the output of journalctl -b-1 attached. ** Attachment added: "prevboot.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1878166/+attachment/5370267/+files/prevboot.txt -- 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/1878166 Title: gnome-shell freezes randomly on nouveau and wayland Status in gnome-shell package in Ubuntu: Incomplete Bug description: The freeze causes the mouse cursor to stop moving and keyboard to stop responding and nothing moves on screen, not even the clock. Curiously the music continues to play (and e.g. sound from youtube video continues to be played even though the video itself freezes and no longer animates on-screen). It appears that the freeze happens quite randomly; I am not able to figure out what it's caused by. Sometimes it's caused by launching the Snap Chromium, or perhaps by a notification shown, but I do not know for sure. I also tried to hunt system logs and/or systemd gnome-shell logs, but I failed to discover some kind of crash dump. Curiously the Ctrl+Alt+F2 key combo stops working. That leads me to believe that it's some kind of kernel+nouveau crash, but I can't seem to discover any kernel panic in the system logs. After the gnome-shell freezes, the numlock light still responds to numlock key presses. However, mashing Ctrl+Alt+Del has no effect, so I'm only able to reboot via Alt+Sysrq+s u b.
