My laptop is no longer suspending. This did not start on upgrade to 22.04, it started more recently and I am trying to debug/diagnose what the cause could be. Can anyone offer suggestions?
It's a HP Omen 15-5000na laptop running Ubuntu 22.04 LTS Gnome 42.1 and X11.
Graphics are NV117 (using Nouveau driver NOT nvidia drivers) and onboard Mesa Intel® HD Graphics 4600 (HSW GT2). To my knowledge I don't have any Nvidia drivers or software installed.
The PC does not suspend and immediately wake so I don't think it's suspending then waking due to USB devices. I think it does not suspend at all, it just goes to the lock screen. Nothing coming up in dmesg and the only entries in syslogs between the sleep request and the wake seems to indicate it could be NetworkManager causing the wake but I don't for sure and I don't know why. There are some gnome-shell messages but I don't know if they are relevant:
syslog:
