Power management in KDE 5 doesn't work

Hello again,

I have noticed that Power Management in Manjaro Plasma doesn't work. Well it work with its default 10 min switch off, but whatever changes you make in there haven't any affect.
Anyone else noticed this? And is there a fix for it ?

best regards
Storm

I found out that it's the powerdevil that is not working properly.
Here's the output:

Switching to unstable to see if it fixes the problem.

Now I'm living on the edge :smiley:
