Hello Linux Geeksters. As you may know, Brightness Controller is an open-source brightness management software capable to manage the brightness from the laptop display, monitor or projector, connected via VGA, VDI or HDMI.
The latest version available is Brightness Controller V2, which has been released a while ago.
In this article I will show you how to install Brightness Controller V2 on Ubuntu, Linux Mint, Pinguy OS, LXLE, Peppermint, Linux Lite, Elementary OS, Debian, Kwheezy, Crunchbang and other Ubuntu and Debian derivative systems.
$ sudo apt-get install python-wxgtk2.8
Download the Brightness Controller Zip archive:
$ wget https://github.com/lordamit/Brightness/archive/master.zip -O ~
$ unzip master.zip
To run the app, do this:
$ cd Brightness-master/src/
$ sudo chmod +x brightness.py
$ ./brightness.py
Also, for an easier usage add this alias:
$ alias bright="~/Brightness-master/src/brightness.py"
And, make it persistent, for bash:
$ echo "alias bright='~/Brightness-master/src/brightness.py' >> ~/.bashrc"
Now, to open the brightness controller, just type bright in the terminal and hit enter.
