A frontend to HAL's power features for KDE.
|
||
|
|
Supports screen brightness, battery level, plugged/unplugged notices, laptop lid closing actions
|
||
|
|
Specification at https://wiki.kubuntu.org/KubuntuPowerManagement
|
||
|
|
|
||
|
|
Issues:
|
||
|
|
- We have to keep polling HAL rather than listening for signals because the Python DBUS bindings
|
||
|
|
don't have Qt mainloop integration
|
||
|
|
- Written in Python so will be slow to load up, will probably port to C++ Qt 4.2 in future
|
||
|
|
- Should also handle UPS and bluetooth batteries
|
||
|
|
- systray applet should be hidden if no battery, but then how do you suspend if no battery?
|
||
|
|
(ksmserver integration please)
|
||
|
|
- Needs lots more testing
|
||
|
|
- Use KUniqueApplication again as soon as dcop problem is sorted outc
|
||
|
|
- dcop calls need patch to dcopexport.py, already submitted upstream
