Power Management not working anymore
by Tychen from LinuxQuestions.org on (#502R1)
Hi there,
running ubuntu 18.04.04 with all updates applied.
Since some days power management does not work anymore.
The screen should turn black after 10 minutes and the system should hibernate after 60 minutes. Both things do not happen anymore. Screens stays active and also the system does not hibernate.
Edit: Windows Manager is Kwin
Since I never had any issues with power management, I have no idea how to debug this, so any help is appreciated :-)
Cheers, Rainer
