Title:
gnome-shell crashes and logs out when disconnecting USB-C cable and
Ubuntu Dash is enabled
Status in gnome-shell package in Ubuntu:
Expired
Bug description:
I recently updated to Ubuntu 24.04 and I noticed that the Gnome Shell
frequently crashes when I disconnect the USB-C cable that connects by
laptop to my screen.
This is sporadic and not easy to reproduce, but when it happens, the
sequence usually is:
1. Run Ubuntu 24.04 with Gnome desktop on a laptop, connected to a screen
with USB-C cable
2. Use it for several hours. I am not able to reproduce this issue directly
after startup.
3. Disconnect the USB-C cable
Expected result: Gnome session should continue on laptop screen after
cable disconnect
Actual result: Gnome session crashes and user is presented with Gnome
login screen
The journald logs from the time of each crash consistently shows these
log lines:

I tried to read
https://gjs.guide/extensions/development/debugging.html on how to
debug this myself, but I can't even find the JavaScript code the error
`resource:///org/gnome/shell/ui/init.js:21 (10c784a70bf0 @ 48)` might
refer to on my system.
**Workaround:** I noticed that if I disable the Ubuntu Dash (app bar
on the left side of the screen), this issue never happens.
