Bug Description
Binary package hint: xserver-xorg-core
The xorg scheduler is currently quite dumb and causes a large number of unnecessary wakeups.
The attached patch originally authored by Arjan van de Ven [1] reworks the scheduler to decrease the amount of wakeups and thus increasing the battery life of the system.
FWIW mandriva has already incorporated this patch [2]
