Powerdevil is a feature rich power manager for KDE. I had been using kpowersave on KDE4.1.3, and now powerdevil looks great !!
General Settings Screen Dimming, Battery Levels and Notification settings. Powerdevil uses knotify with a sound event and customizable messages for it’s notifications.
Powerdevil provides 5 default power profiles that are customizable:
- Aggressive Powersave
- Xtreme Powersave
Provides options to create new/edit existing profiles. For each profile, the following fields are customizable:
- Screen brightness
- Kwin compositing toggle on/off
- Computer idle actions
- Power/Sleep/Lid button actions
- CPU frequency scaling
- Turning off CPUs
- Screen power management
Also provides options to Import/Export and clone profiles.
This screen lists all system capabilities that Powerdevil can make use off.
Sadly, my laptop does not support turning off of CPUs. Everything else work perfectly.
Powerdevil is most likely to be integrated in KDE4.2
At first, I was a bit surprised after not seeing a systray icon, but well, I don’t need one really. I use the Battery Status plasma in 4.1.3, while the same widget integrates well with powerdevil in 4.2
This is definitely worth trying..
