Small tool for linux to adjust screen brightness.
npm install -g brightnessctl
Tested on the Dell XPS13 running Arch.
To adjust the screen brightness simply run
sudo brightnessctl
It will print an interactive slider that looks like this:
Use <left> and <right> to adjust brightness
[####### ] 15%
You can also adjust the brightness with a cli argument like so
sudo brightnessctl 50 # sets the brightness to 50%
PRs that add support for more distros welcome.
