The problem I was facing for sometime is setting brightness of my laptop that is running Ubuntu 12.10. Unfortunately this function is not available in my laptop. So I started my investigation to get this functionality. Then I found the xrandr command. A similar is xbacklight command, but it’s not of much use. xrandr is very typical to use, believe me it’s not handy to use for a day to day practice. So I wrote a shell script to use xrandr command easily.
You can clone the shell script from email@example.com:manvendrasinghig/brightness.git using the standard git clone url command from a terminal.
