Thanks a lot everybody for your help. Interestingly, on my machine both methods work.

Check if you hav e a class backlight device in /sys (iotw something under /sys/class/backlight). If so you should be able to control the backlight via hal. You can test the kernel by echoing values into the brightness file Sjoerd -- You can't push on a string. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

I can change the values in /sys/class/backlight/acpi_video0/brightness but they have no impact on the brightness. Charles, setting "xrandr --output LVDS --set BACKLIGHT_CONTROL native" should make at least xbacklight work, but for HAL which relies on the ACPI interface, this is up to the kernel.
