[11:48] <napalm> Hello! I have some problems on 5.4.0-77-generic with my Dell XPS 15. after messing with bumblebee and video drivers I've broke the system suspending and hibernation. On systemctl suspens/hibernate the screen goes black for 15 seconds, and then it shows new login screen. After logging in it seemingly starts new session and on power off it kills this session, and shows login screen again. I've retraced all steps I did since last time hibernation/suspending
[11:48] <napalm>  worked, and tried to change it back, but it didn't help. Can anyone try to help me please?
