Title:
Gnome shell freezes when plugging in external display
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
I have a Lenovo Thinkpad X1 Yoga with Ubuntu 22.04 and a dock for it.
If the laptop is in the dock and I plug a monitor into the display
port gnome shell freezes. When this happens I can still go to other
ttys. This exact setup used to work for Ubuntu 20.04 so I assume it
must be connected to wayland somehow.

Description: Ubuntu 22.04 LTS
Release: 22.04
