UPower - display backlight

[Serghei Amelian]

Hello,

I'm one of Trinity Desktop Environment developers and currently my task is to 
implement a new power management infrastructure.

So far I developed a battery monitor, based on UPower. The current problem is 
controlling backlight for displays. Using XRandR externsion is not feasible, 
because is too slow ( 
http://lists.x.org/archives/xorg/2008-May/035007.html ), I tried it already.

The question is: will be possible to include into upower support for 
controlling brigtness via ACPI (similar to 
org.freedesktop.UPower.KbdBacklight) ?

Thanks
