Hello everyone,

I've got a laptop that cannot adjust brightness using functions keys
so I wrote a little program that use the acpi_video(4) driver and
sysctl(3).

The program adjust brightness using one arguments : up or down. Check
this example :

markand at Melon ~ $ brightness up
switching to 46
markand at Melon ~ $ sysctl hw.acpi.video.lcd0.brightness
hw.acpi.video.lcd0.brightness: 46
markand at Melon ~ $ brightness down
switching to 43
markand at Melon ~ $ sysctl hw.acpi.video.lcd0.brightness
hw.acpi.video.lcd0.brightness: 43

So if you canno't adjust brightness using function keys on your laptop
use this program with any bindkey in your window manager :
