However, that doesn't work. The options I have for xrandr BACKLIGHT_CONTROL are native, legacy, combination and kernel, and none of them makes any difference.
The only difference to my comment #2 is that now I can see and select different backlight control methods. (Should have written xrandr --prop instead...)
Cheers for the hint, executorvs!
