Comment 24 for bug 1970065

I'm also facing this issue with Ubuntu 22.04.1 running on a HP Z800 tower.

In my case, every time I ask for a shutdown, or reboot, windows manager dies but I can still see all windows contents, and even interact with applications (some of them), but not able to reboot from GNOME desktop.

I can however login remotely to my Desktop, and then do:

sudo poweroff

and it work correclty, but not from GNOME desktop.
