Description Salvo "LtWorf" Tomaselli 2015-07-27 22:40:51 UTC

I am using the plasmoid to show the battery status. But powerdevil is not installed; because I don't want any action. I just need to see how much charge is left.

The plasmoid has a checkbox to disable power management. But whether it is checked or not, the screen will be locked if there is no input for a while.

After installing powerdevil, the checkbox about disabling power management 
actually works. Without installing powerdevil, the screen will be locked after 
a timeout and there is no way to stop or configure that.

I find it a bit weird, I suppose that the screen locking functionality should 
be moved inside powerdevil.

Reproducible: Always

Steps to Reproduce:
1. Remove powerdevil, if you have it
2. Enable (or disable) power management in the plasmoid
3. Wait
4. The screen will lock


Expected Results:  
No power management

PowerDevil is providing the freedesktop inhibition interface where plasma would send an inhibition to, so without it, it cannot work obviously.
