Set Screen Brightness from Terminal

We can set screen brightness from terminal by using xbacklight. Intially we have to install it before using. Open your terminal and type as

sudo apt-get install xbacklight

and then to set brightness to 10% more execute the command as

xbacklight -inc 10

To decrease brightness by 10%

xbacklight -dec 10

If you want to set the brightness to some level then, you can use the command as

xbacklight -set 50

The above command will set the brightness to 50. It will range from 0 to 100.
If you have any issues you can use comments to let me know.
Hope that helps.
