Is there a way to control the keyboard backlight on a HP laptop in software? Of course there is the keypress (fn+F5 in this case, Pavilion), but that is a toggle. Also, the fn key is never exposed to the OS, so using e.g. xdotool to inject a keypress is not possible. I have tried the xset command with numerous parameters, but found nothing that worked for the backlight. Looking for help!
