Title:
Crashes on DP hotplug (wl_registry@2: error 0: invalid global
wl_output (29))
Status in gnome-shell package in Ubuntu:
New
Bug description:
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.)
