Default Re: Linux backlight driver

When you type
cat /sys/class/backlight/nvidia_backlight/brightness
do you get a result?
Also try as root
echo 50 | tee -a /sys/class/backlight/nvidia_backlight/brightness
to check if you can control the brightness.
I haven't changed anything else in the source. Also Fn keys don't work, only the slider of powerdevil.
