Title:
Disconnecting monitor crashes shell (wayland, gnome)
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
This bug has been persisting since I've bought an external monitor for
my laptop and started using Wayland (first on Ubuntu 20.04) until
today (Ubuntu 21.10).
It isn't consistent, but it occurs about 90% of the time when I'm on
Wayland. On Xorg, this has never occurred.
When I unplug my USB-C monitor from my laptop, the laptop screen
freezes for a while before presenting me with the login screen. When I
log back in, all my open applications have been shut down.
I assume Mutter crashes, taking the entire session with it.
Dmesg doesn't seem to contain anything useful.
A lot of other people seem to have this problem (see
https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1733127),
but all have been asked to file their own bug reports, so here I am.
