Enable Night Light in Ubuntu Linux: A Quick Guide

Ubuntu Linux’s Night Light feature automatically makes your screen warmer to reduce blue light, helping your eyes feel less tired and potentially improving sleep.

Night Light is a built-in tool that shifts your screen’s colors toward warmer tones, especially as the day ends, mimicking natural light.

This is really helpful if you often use your computer at night. You can turn on Night Light directly from the Display settings in Ubuntu 22.04 LTS and newer versions.
