I was infored that this ability has been discountinued in favour of the backlight utility, so I gave up and wrote the following devd rule: notify 10 { match "system" "ACPI" ; match "subsystem" "Video" ; match "type" "brightness" ; action "/usr/bin/backlight $notify"; }; This changes brightness by tiny 1/100 steps, but this is by desing of the HP engineers...
