Wierd problem - Backlight dont start...

[hirolau]

Hi, I just started my computer and for some reason my xorg.conf was gone and mesa was the running driver. I tried to create i new but now I got a strange problem.

When I start the computer, the back-light of the LCD screen is of. The back-light starts if I adjust the brightness of the screen, then everything is back to normal. This happens every time i start the computer, switch between (ehh, I dont know what it is called Ctrl+Alt+number) or when I change the resolution.

Does anyone know why this happens and how to fix it? I use Kubuntu 9.04 with radoenhd 1.2.5

Do you have something in your xorg.conf that calls your device with identifier X1600?

He should probably change X1600 to Configured Video Device. :3
