Find a way to control the screen brightness from the Unity panel? Today I’m going to show you this brightness app which is inspired by the original Gnome brightness applet. With this indicator you can set your screen brightness in Ubuntu Unity.
You can set your screen brightness by using the indicator menu or the scroll wheel of your mouse over the indicator icon. Also it supports to control screen brightness with custom keyboard shortcuts.
To install the indicator, hit Ctrl+Alt+T to open terminal, copy and paste following commands and run one by one (Supports for Ubuntu 13.04 Raring, 12.10 Quantal, 12.04 Precise, 11.10 Oneiric):

sudo apt-get update
sudo apt-get install indicator-brightness
Add these commands to your custom keyboard shortcuts to control brightness with your keyboard:
