In dom0 terminal:
cd /sys/class/backlight
ls
cd into whatever is listed here
sudo su
echo 100 > brightness

That last number will vary depending on your model and how bright you
want it. Don't do low numbers unless you can type blind.

Thanks man.

Thanks man,
Had some temporary success.

So this went well for my Qubes 4.0

cd /sys/class/backlight
ls
cd intel_backlight
sudo su
echo 80 > brightness

Then it goes rather quite dark, seemingly regardless of the number I select. And once I change it, changing it again using the echo doesn’t work.
Also, how would you make it permanent? After sleep mode and restarts max brightness returns.

Check "cat /sys/class/backlight/intel_backlight/max_brightness", your
range of allowed values might be different than mine.
