This is a simple program to set monitor brightness using xrandr.
I made this because Ubuntu does not come with a built-in way to change monitor brightness.
go install github.com/MicahParks/bright@latestSet brightness to 80%
$ bright 80
Brightness set.
Only set between 20% and 80%
$ bright 101
Must be between 20 and 100.
Set brightness to 100%
$ bright
Brightness set.
