The brightness keys don't really work when installed. You can tinker with acpi_ibm(4) and acpi_video(4) if you're interested.
Brightness can be increased or decreased with
backlight -f /dev/backlight/backlight0 incr [value]andbacklight -f /dev/backlight/backlight0 decr [value]respectively. Check the man page of backlight for further information.Add a key binding to make it work like fn keys.
