Hi,
I'm on 4.2 beta2, and my problem is that my laptop's LCD never powers off ! It goes black, but the backlight is always on. I have removed kpowersave, which I used to use previously, and now using powerdevil. It simply doesn't turn off. The VGA card is nVidia, and `xset q` returns
DPMS (Energy Star):
  Standby: 0    Suspend: 0    Off: 0
  DPMS is Enabled
  Monitor is On

Using, `xset dpms force off` does power off correctly. In fact, using
qdbus org.kde.powerdevilsystem /modules/powerdevil org.kde.PowerDevil.turnOffScreen
also does power off correctly. So powerdevil is able to power off the screen if it wants to .. then why is it not doing that ?! How do I even start debugging this .. It is very annoying, as it's burning off hours from the LCD's lifetime. Any tips are welcome

Regards
