How to Turn Off/Disable Automatic Brightness on Ubuntu

Turning off automatic brightness on Ubuntu!

Source: wikipedia

You can find the option to toggle automatic brightness under Power Settings.

Press the Windows (known as Super or Meta Key in Linux World) key. This will bring up the area of activities and you can search the settings here.

In the Settings app, go to Power Settings from the left side bar. Under the Power Saving option you will see the Auto Brightness option.

Toggle the button to turn it on or off.

Alternative method: Turn off automatic brightness on Ubuntu using the terminal

The GNOME-based desktop environment can access brightness settings via the command line.

Open a terminal in Ubuntu and use the following command to turn off automatic brightness:

gsettings set org.gnome.settings-daemon.plugins.power ambient-enabled false

Similarly, you can set the value to true to enable the automatic brightness again:

gsettings set org.gnome.settings-daemon.plugins.power ambient-enabled true

Automatic brightness helps save battery life but it can also be annoying, as I had said before had I wish there was no way to automatically ignite a certain level of brightness.
