I have a Samsung Series 9 NP900X3C, which has a Intel HD Graphics 4000 chip. When I use the the Fn keys for changing the brightness, it shows me a nice OSD and sets the value in
However, this doesn't do anything to the actual screen. Instead, I have to
echo $number >> /sys/class/backlight/intel_backlight/brightness
How do I fix this keybinding?
The same goes for the keyboard illumination, I've found the place in
/sys/call/leds/ to set it, but the Fn key combination does diddley-squat.
