Title:
gnome-shell crashed with SIGSEGV in
meta_window_update_for_monitors_changed()
Status in gnome-shell package in Ubuntu:
Confirmed
Bug description:
Pair this with bug #1723615: This one actually happened first, and was
presumably the event that ended my gnome desktop session. Then the
other one happened about 18 minutes later and happened to gdm's gnome-
shell. Both occurred while I was away from the computer and the system
should have been in displaysleep but not suspended.
