I cannot seem to make the system go to sleep properly (more details later) since a few days. This is since after an update to a bunch of Nvidia drivers, but staied in place after an update to 22.04.
However doing this:
sudo /lib/systemd/systemd-sleep suspend
works perfectly, and on the other hand this:
sudo systemctl suspend
fails in the same way so I guess that the failure must happen between the two.
Specifically, the failure looks like this:
- it tries to suspend
- bounces back to a login screen
- then logs into a new session or
- sometimes bounces again to a login screen
- and from there to a new session
- and sometimes it just gets stuck on a black screen with arrow cursor, so I have to force reboot
The machine is a Lenovo ThinkPad P50 i7-6820HQ and there's more than enough disk space to go by.

What should I look into to pinpoint the issue?
