On my Raring, KDE, Ubuntu 3.8.0-30.44-generic, bumblebee removed, BIOS SATA Compatible (to allow nvidia drivers to work, http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Nvidia_Accelerated_Graphics_Driver, note that that also disables the intel card which does not appear anymore in lspci), only default kernel parameters:
The plasma widget for screen brightness (actually battery monitor) is able to change the brightness. And automatic brightness change from KDE system (when power is unplugged) works also. However, the hotkeys do not trigger any change.
Is there any debug files that would be useful?
