Reduce lowest brightness

Zorin 17 lowest brightness is still too bright for me. It's possible to custom the value of lowest brightness?

Run xrandr --listmonitors and note the moniter name then run xrandr --output DISPLAY_NAME --brightness 1 you can adjust the value of 1 from 0.1 to 1

This will only work if you are using Xorg.

I use version 17.

It will work regardless, just make sure you are using x11

It's also works on Zorin 17 (Wayland).

This morning when I checked --listmonitors, it showed "eDP-1". And the method above worked.

But for some reason this afternoon I tried again -- listmonitors no longer displayed eDP-1, but XWAYLAND0. And the method above no longer works.

Meanwhile, since the beginning of OS Zorin 17 I have been using Wayland, there is no Xorg option on the login screen.

Why did it happen?
