Installation via PPA

Thanks to package maintainer @apandada1, we have PPA repository For Ubuntu and likewise users:

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

Manual Installation

First, install PySide2.

sudo apt install python3-pyside2.qtcore python3-pyside2.qtgui python3-pyside2.qtwidgets python3-pyside2.qtnetwork

Somtimes it is not enough to install and integrate PySide2, so you might also try installing PySide2 using pip3.

pip3 install PySide2

We prefer using --user while installing PySide2 using pip. Installing it in virtual environment may not work as intended.

Next, download the latest zip file from here.

Extract it and open a terminal. Change directory to the Brightness folder. Next type this command:

python3 src/init.py

Achean also created a detailed tutorial on how to install it in Debian based on his experience. You can find it here.

Features

The following features are implemented:

1. Brightness Control
2. Saving color profile
3. Loading color profile

We are working on the following features and plan to release these through version 3:

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

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

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.

Requirements

There are several requirements:

1. python3
2. python3-pyside2.qtcore, python3-pyside2.qtgui, python3-pyside2.qtwidgets, python3-pyside2.qtnetwork
3. xrandr support in your system

Bugs

Please test v2.3. Reporting bugs is appreciated.
