I don't know if this is different of debian, but I think the universal way to so this is to modify `/sys/class/backlight/edp-backlight/brightness`.

Easiest way is to run
Code:
# cp /sys/class/backlight/edp-backlight/max_brightness /sys/class/backlight/edp-backlight/brightness
To set the backlight to max brightness.

(The "#" means you need root permissions to do this, on debian I believe this is done with `su`, but you may also have `sudo` installed)

I also found out I could use brightnessctl to control, I use sudo "sudo brightnessctl set <value>"
