I can see the option to reduce the brightness of the screen on my laptop but not on my desktop. Is there a way to adjust this on my pc?

Do you use latest version of elementary OS?


Install Brightness Controller with the following commands:

sudo add-apt-repository ppa:apandada1/brightness-controller
sudo apt update

For Version 1 with up to 4 Monitor Support:

sudo apt-get install brightness-controller-simple

]([![Brightness Controller Version 1

For Version 2 with Multi Monitor Support and other features:

sudo apt install brightness-controller
