Ubuntu – the brightness controls

18.04brightnesssystem-settings

I installed Ubuntu 18.04 recently. I have been using Ubuntu for over 5 years I know that the brightness controls are inside the Power section in the settings but they are not there anymore. Searching for brightness still brings Power section in settings as the only result in gnome-shell but I can't seem to find it.

Can someone please tell me how I control my brightness in Ubuntu 18.04

Here is a screenshot of power tab in settings
Power Settings no brightness control

Best Answer

I took a moment searching the problem in the internet, one of the proposed solutions : 

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

Normally, after this, you will have the brightness controller. You can find it under Settings>Power menu or search it in Dash.
