Public bug reported:
I switched to a new external monitor at work today. I cannot reproduce
the exact sequence of events, but it was basically: plug in external
monitor (via DisplayPort), suspend laptop, unplug that monitor and plug
in another one, resume laptop. At that point I was staring at the GDM
login screen because gnome-shell had crashed on me.
(It's hard to understand what happened exactly, from the journal, but it
may've been Xwayland that crashed -- I've an Xwayland crash file in
/var/crash with a matching timestamp -- but the entire GNOME session
died soon afterwards.)
Highlights from journalctl:
