This has happened a few times:
User1 on F8 console
User2 on F9 console
User2 playing streamed music in Firefox
Switch to User1 on F8
Music stops playing
After around 30 sec: Screen blanks Drum roll Login screen, on F9 The previous X session on F9 has crashed out, all the work on open windows gone.
I found the following log messages, but ultimately perhaps it is Xorg or nvidia that should take responsibility for the X session crash?
