Public bug reported:
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.
