How to enable night light feature on Ubuntu

The Night Light feature in Ubuntu reduces eye strain by minimizing blue light emissions, which can disrupt sleep patterns. It adjusts the screen to warmer colors, making it more comfortable to use during nighttime or in low-light environments. This feature is particularly useful for users who work late or in dark settings.

In recent versions of Ubuntu Desktop, Night Light is integrated directly into the system settings. Users can easily access it through the Display section. The feature allows automatic adjustments based on sunset and sunrise, or users can manually set a schedule to match their routine.

For technical users, configuring Night Light ensures better visual comfort and helps maintain productivity during extended work sessions. Customizing the settings is straightforward, and once configured, it requires no further manual adjustments.

1. Open Settings from the application menu.
2. Go to the Display section in the left sidebar.
3. Select the Night Light tab.
4. Toggle the switch to enable Night Light.
5. Adjust the color temperature using the slider.
6. Set the schedule to Sunset to Sunrise for automatic timing.
7. Close the Settings application.
