Do you have the following file:
$ cat /sys/class/backlight/intel_backlight/brightness
40
$
If so, do you get brightness changes when you write values
into it:
# printf '%s' "60" > /sys/class/backlight/intel_backlight/brightness
Cheers,

OK, I can write the values to
/sys/class/backlight/intel_backlight/brightness
The default is 15040, which seems to be the maximum.
Nothing visible changes between 15040 and 13000.
60 is very dark.
It therefore looks like an exponential function.
I have to see how I can represent this in a function to use it with the
fn-keys.
