Brightness Controller

This is version 2.4 of Brightness Controller for Linux. It supports an arbitrary number of displays and also allows changing the color temperature across displays!

If you like this, do not forget to give us a Star! That's the only way we can estimate whether people are using it or not since we do not collect any data, at all. People already did!

Installation via Pip

pip install brightness-controller-linux

Requires at least python3.8 or above, and PyQt5 or above. This installation method is fairly new, so will really appreciate if you let us know if everything is working as intended or not at your end. :)

Features

The following features are implemented:

Brightness Control
Saving color profile
Loading color profile

Brightness Controller changes Red, Green and Blue color ratios in the screen through color profile at software level using xrandr.

We might implement the following features in the future:

Rewriting GUI to integrate both Brightness Controller simple and normal
Auto-loading of color and brightness settings based on profile
Checking for update

We work on this in our spare time, so can not really promise when the v3 will be released. The current version available is stable and should work as intended.

Bugs

Please test v2.4. Reporting bugs is appreciated.

Wayland Bugs

Wayland does not provide a way to control the brightness of primary/external displays, so Brightness Controller won't work. It has been reported several times, and we are aware about it. Really, it is out of our hands.

Can I have just brightness sliders - For Controlling Four displays at the same time?

We got you covered! Try version 1.2.8/simpler version of Brightness Controller. It was written in Python2, which has been deprecated, and some of its dependencies (e.g. WxGTK for Python2) are not available in recent versions of Ubuntu. It is only available for Ubuntu 20.04 and previous versions.

To install, simply do this:

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

Further details are available here

Please note that the simple version may not work properly in newer versions of Linux. Unfortunately we can not provide any more updates to the simple version.
