[2] helped! Now i can change the backlight with xbacklight -set value. As you said this only works for the intel chipset with is the graphic adapter i use when i am using the laptop mobile. So its annoying that i cant change the brightness wit the nvidia card but not as much of a problem as it was with the intel chipset. As the nvidia driver is a propietrary one, i dont think that is a thing i or anyone here can solve? Thank you so much! Is the brigthness issue now still a bug or should i delete it from bugzilla? regards Sebastian
