Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:
1. Run these commands:
journalctl -b0 > journal.txt
journalctl -b-1 > prevjournal.txt
and attach the resulting text files here.
2. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
3. If step 2 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.
Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
Gnome session crashes if monitor is disconnected
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
Recently installed and fully updated Ubuntu 24.04
I have to switch my monitor/keyboard/mouse between two computers.
Every time when I let the screen lock time-out elapse, my desktop
session crashes and I have to log on again (but the system keeps
running). As long as the screen is not locked, I can switch back to
the running session normally.
I do not know whether my user session crashes on screen lock or on
switching the monitor back to this computer.
I use an nVidia GeForce RTX 4070 video card connected through
DisplayPort to an LG Ultrawide 40" monitor. The display server is X11.
It may or may not be relevant to this problem that quite often after
the monitor is re-awakened from sleep, some interface/window icons are
replaced with blank grey colour (i.e. minimise/maximise icons on
window bars, folder icons in Files, &c. The application window
contents seem to be intact, but entire windows (I mostly see this with
FireFox) often take a long time to be drawn, sometimes not until I
hover the mouse pointer over them.
