I was testing some other issues today and tested this one as well.
I am currrently running Ubuntu 13.10 Saucy with kernel 3.11.0-15-generic
I can confirm that this problem still exists:
- The fn F6/F7 hot keys for brightness show the light bulb and slider but have no effect on screen brightness
- As root, I can echo numbers into /sys/class/backlight/intel_backlight/brightness to change the screen brightness up and down
So it appears the disconnect is between the hotkeys and that file. When I use the hotkeys, that file does not change. I'm assuming it should be changing?
