How do I change screen brightness in Dietpi

[computerc]

Hello,

I need help getting the screen brighter using Dietpi, running on debian bullseye.

[user18130814200115]

running on debian bullseye.

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>"
