Hello Linux Geeksters. As you may know, Brightness Indicator enables the users to control the screen brightness via a dedicated indicator from the applet.
The latest version available is Brightness Indicator 0.4, which has been recently released.
In this article I will show you how to install Brightness Indicator 0.4 on Ubuntu 15.04, Ubuntu 14.10, Ubuntu 14.04 and Ubuntu 12.04 Precise Pangolin.
Because it is available via PPA, installing Brightness Indicator Ubuntu 15.04, Ubuntu 14.10, Ubuntu 14.04, Ubuntu 12.04 and derivative systems is easy. All you have to do is add the ppa to your system, update the local repository index and install the indicator-brightness package. Like this:
$ sudo add-apt-repository ppa:indicator-brightness/ppa
$ sudo apt-get update
$ sudo apt-get install indicator-brightness
Optional, to remove indicator-brightness, do:
$ sudo apt-get remove indicator-brightness
