In some discussions I read that it should be possible to set the brightness via /proc/acpi/video/VID/LCD/brightness, but this seems not to be supported:

cat /proc/acpi/video/VID/LCD/brightness
<not supported>

Again, I can change the brightness via the FN-keys - only changing by software doesn't work - and any program trying to change the brightness hangs with an error message:
