Problem

My laptop's screen remains too bright at night, even at the minimum brightness.

Solution I'd like

A tool that lets me change brightness beyond minimum brightness.

What I've tried already

xrandr: Brightness remains the same regardless of the value I enter.
xgamma: Again, brightness doesn't change no matter what number I enter.
Brightness Controller: Does not work in Ubuntu 22.04.
Redshift: No longer functional.
Night Light: Only changes color, not backlight or brightness, even if artificially.

Try "light", available in the Ubuntu repositories – vanadium Jul 20 '22 at 10:07
Most likely your tools are not working because you are using Wayland, and they are designed for Xorg. If you switch to xorg, most of these options should work. – Esther Jul 20 '22 at 20:02

The Gnome Shell extension Alpha Tint has solved the issue for me in Ubuntu 22.04.1 LTS (Wayland).
