Enable Night Light in Ubuntu Linux: A Quick Guide

You enable Ubuntu Linux’s Night Light feature to reduce blue light emission from your screen, which helps prevent eye strain and improves sleep.

Night Light is a built-in Ubuntu utility that automatically shifts your screen’s color temperature to warmer tones, especially after sunset, to simulate natural light patterns.

This is a fantastic tool if you frequently use your PC in the evening. For instance, you can easily activate it in Ubuntu 22.04 LTS through the Display settings.
