Brightness Controller – Take Complete Control of Your Monitor’s Brightness

Brightness Controller for Ubuntu
Written by Martins D. Okoi

If you have spent long hours on your PC before then you must know by now how your eyes react to your screen’s bright light.

I imagine that for many users, an almost blinding screen brightness is in their favour to get work done. But for users like myself, I like my screen brightness a bit on the dim side.

Brightness Controller is an application that allows users to adjust the brightness of their PC’s external monitor independent of their main display panels.

Brightness Controller will allow you to adjust your brightness to any level between 1% and 100% and apparently, it can be used in conjunction with external monitors!

For advanced users, there exists Primary Brightness, Secondary Brightness, and Color Temperature options. The color temperature option will allow you to conveniently change RGB values depending on several display types.

Features in Brightness Controller

  • External Monitor Adjustment – necessary adjustments to external monitors from an independent source.
  • Brightness adjustment – control the degree of your monitor’s brightness without restrictions.
  • Color temperature – tweak RGB values per-display.

Brightness Controller can be installed on Ubuntu 12.04 and later – together with any distros with support for the developer’s official PPA:

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

You should be informed though, that as at the time of writing, Brightness Controller works via xrandr and lacks support for Wayland. So if that’s your preferred session then you will just have to wait till later to test the app for yourself.
