Understanding Night Light

What is Night Light?

Night Light is a built-in feature on Ubuntu that dynamically adjusts the color temperature of your screen. By reducing the amount of blue light emitted, especially during the evening, it aims to promote better sleep and mitigate eye strain.

Activation and Basic Customization

Enabling Night Light:
  1. Open the system menu and select “Settings“.
  2. Navigate to “Displays” and toggle the switch to enable Night Light mode.

Adjusting Color Temperature via Settings:

  • In the “Night Light” section, use the slider to set your preferred color temperature.
  • Retrieve the current temperature setting using the command:

gsettings get org.gnome.settings-daemon.plugins.color night-light-temperature

This command will display the current Night Light temperature value in Kelvin. For example:

uint32 4000

Advanced Customization: Custom Schedule

  • Night Light can automatically activate based on your local sunset and sunrise times.
  • Navigate to “Settings” > “Privacy” > “Screen Lock” and toggle the switch for “Automatic Screen Brightness” to enable the custom schedule.

Advanced Customization: Command Line Options

For advanced users, customize Night Light via the command line using the following:

gsettings set org.gnome.settings-daemon.plugins.color night-light-temperature 4000

Replace “4000” with your desired color temperature value.

Real-Life Scenarios

  1. Enhanced Reading Experience:
    By enabling Night Light during late-night reading sessions, users can experience reduced eye strain and a more comfortable reading environment.
  2. Photography and Design Work:
    Professionals engaged in photography or design work can fine-tune the color temperature to ensure accurate representation of colors on their screens, even during evening editing sessions.
  3. Promoting Better Sleep:
    Utilizing Night Light’s custom schedule feature aligns the display with natural circadian rhythms, potentially leading to improved sleep quality.
  4. Reducing Blue Light Exposure:
    Night Light aids in minimizing exposure to disruptive blue light, making it a valuable tool for individuals who spend extended hours on computers before bedtime.

Personal Experience

In my own experience, I have been using the Night Light feature for an extended period, and I’ve found that setting the Night Light color temperature to “6000” provides a perfect balance for my preferences. This setting not only reduces eye strain during late-night work but also enhances the overall visual comfort, making my computing sessions more enjoyable.

Embracing the Power of Customization

Experiment with the settings to find the perfect balance that suits your preferences. Whether you’re a night owl or prioritize a good night’s sleep, Ubuntu Night Light feature provides a customizable solution for a more enjoyable and eye-friendly computing experience.


Mastering Ubuntu Night Light feature unlocks the potential for a more comfortable and personalized display experience. By embracing the power of customization, users can tailor their computing environment to align with their preferences and well-being. As we spend more time in front of screens, it’s essential to leverage tools like Night Light to enhance our digital experiences and prioritize our health.
