How to dim your screen below the minimum on Linux

2023-01-28, in:

If you want to dim your screen below minimum you can use xrandr to modify the colors displayed. To make it darker you can use for example:

xrandr --output eDP-1 --brightness 0.4

Warning: If you set it to a crazy value you can make your screen unreadable (all black or white)!

Find the --output parameter value(s) for your computer with:

xrandr -q
