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
