Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.
3. If step 2 also failed then apply the workaround from bug 994921,
reboot, reproduce the crash, and retry step 1.
Please take care to avoid attaching .crash files to bugs as we are unable to
process them as file attachments. It would also be a security risk for yourself.

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.
