In Desktop Summit Richard Hughes Dario Freddi and I talked about
Backlight, the current situation as far as I know goes as follow:
There are 2 ways of managing display backlight, both GNOME and KDE have
almost equivalent implementations:
-XRandR: If the Driver supports backlight we use it, the code in both
projects is almost duplicated or even copypasted, in the case of KDE can
be found here:

-Via /sys/class/backlight interfaces: Again both GNOME and KDE are using
an almost equally code, one written in G* and the other in Qt*
KDE code can be found here:
http://goo.gl/d4OLa
So, we proposed to unify both efforts into a single shared library, but
so far nothing happened.
I'd like to see this library happen, one of the benefits will be to
unify both implementations are working for the 99% of cases but the
remaining 1% is different mainly because of the interface order we use.
