I have a serious problem with 'systemctl hibernate' command.
It hibernates and resumes just fine, but in the last stage of resume, it completely shuts down my laptop's screen, so I cannot see anything even though I know the system resumed just fine and the desktop is running. I can even hear the music files being played that were left playing during hibernation.
If I hibernate using
sudo hibernate -F /etc/hibernate/tuxonice.conf
the system hibernates and resumes in the same way, except the screen does not get turned off upon resume (but I don't want to use this method cause there are other issues with it).
journalctl -b -u systemd-suspend or hibernate returns nothing.
What can be amiss here?
I tried running xrandr to enable screen after hibernation, but I cant get it to work properly, either.
