How to Enable Automatic Brightness in Ubuntu Linux
Automatic brightness in Ubuntu Linux adjusts your screen brightness to match the light around you. This built-in feature uses your laptop’s light sensor to dim the display in dark rooms and make it brighter in the sun, which saves battery life and cuts down on eye strain.
Laptops running Ubuntu 22.04 LTS and later support this feature right out of the box. You can turn it on in a few clicks through your display settings so your screen always matches your room.
Open System Settings, click on the Power tile, and then toggle the Automatic Screen Brightness switch to the On position. This feature uses your device’s light sensor to adjust screen brightness automatically.

Locate the Automatic Screen Brightness toggle inside the Power Saving section and switch it to On. This feature helps conserve battery life by dimming your screen when it's not needed.
That's it! You can now close the settings app.
