Howdy Guys,
As we all know brightness can be controlled from most laptop keyboards now. Even the mouse has long been used to increase and decrease LCD back light brightness.
But, today we’re going to use a command line tool called xbacklight.
Xbacklight is available system default software repo.
Installation
On Ubuntu:
sudo apt-get install xbacklight
Fedora:
sudo yum install xbacklight
Arch:
sudo pacman -S xbacklight
Usage
All you need to do is to open terminal.
To increase or decrease, you add the value or percentage to increase or decrease by.
For example: Increase to 100 command is:
xbacklight -inc 100
Decrease to the minimum will be:
xbacklight -dec 100
Enjoy!
