Brightness control using xrandr configuration utility

A Bash script that can help you change your brightness level by using a custom shortcut.

Dependencies

Install bc if it isn't already. We will need bc to work with decimals since the bash shell ignores the decimal point.

sudo apt-get install bc

Installation and configuring shortcut

1. Copy the adjustbrightness.sh file to your home directory

2. Create a custom keyboard shortcut in Ubuntu settings

3. Give it a name and custom shortcut

4. Finally paste "./adjustbrightness.sh 0.1" and "./adjustbrightness.sh -0.1" to the command section of increase and decrease shortcuts respectively
