This brief guide explains how to control the brightness using Brightness Controller application in Ubuntu and its derivatives such as Pop!_OS, Linux Mint and Elementary OS.

Of course, there is also a CLI utility called "xrandr" that makes this job much easier from command line. For those who prefer GUI-based applications, "Brightness Controller" might be a good choice.

Brightness Controller app is used to control the brightness of your display, save a color profile, and load a profile from the saved list. It is completely free, open source and is written using "Python" programming language.

Install Brightness Controller In Ubuntu

The developer has made a PPA for Ubuntu and its derivatives. So, installation won't be a big deal. To install it, run the following commands one by one:

$ sudo add-apt-repository ppa:apandada1/brightness-controller
$ sudo apt-get update
$ sudo apt-get install brightness-controller

Please be mindful that it is compatible with python2 only.

The usage is absolutely easy. Once installed, launch "Brightness Controller" from Menu. This is how the default interface looks like.

$ sudo apt-get update
$ sudo apt-get install brightness-controller-simple

I have been searching for this for months. I used to use f.lux on my old windows but ditched them office wide earlier this year and installed Linux Mint in everything.

This works perfectly!

Thank you *very much*!
