![]() Visit to get your Latitude and Longitude. How to Set Latitude and LongitudeĪdd -l switch with redshift command to add Latitude and Longitude of your location. I have adjust the screen brightness 50% on night. # redshift -t 5500:4000Īdd -b switch with redshift command to adjus screen brightness (between 0.1 to 1.0). How to set Day/Night time temperature ?Īdd -t switch with redshift command to add Day and Night time temperature. I have set 3500K color temperature, this is quit extreme because default night temperature for redshif is 3700K, anyhow keep change the temperature value until you found the suitable one. To set one shot manual mode to set standard color temperature, use the capital -O option with redshift. Do you want to know more about redshift ? If yes, simple play around the options to find the right color temperature for you. To set one shot modeĪfter you start redshift, it will automatically get the location and set the color temperature of your screen according to your surroundings. Here choose the info to see the status of Redshift. Install both packages redshift & redshift-gtk, redshift-gtk provides a system tray icon to control Redshift easily.įor Debian users, use APT Package Manager or Apt-Get Package Manager to install Redshift. Most of the major Linux distributions by default have the redshift package, so simple use the Package Manager to install it. Make a note, Redshift only works with Xorg and Wayland is not supported yet but Gnome users can install with help of GNOME Shell extension. It will automatically do the job as you expect. ![]() There is no configuration required for redshift, so simply install the app then leave. Redshift will continuously update the color temperature at regular intervals. ![]() If you care too much about color accuracy then blindly use this program. Even, if you customize the gamma ramps, the system will overwritten the default one. The color temperature is changed by setting appropriate gamma ramps. Linux and Unix systems color temperature is set with an X server extension. During the day, the color temperature set to match the light from outside, typically around 5500K-6500K (default is 5500K). Night time color temperature is very low, between 3000K-4000K (default is 3700K) and the color temperature set to match the lamps in your room. During twilight and early morning, the color temperature transitions smoothly from night to daytime temperature to allow your eyes to slowly adapt. Visit to get your Latitude and Longitude.Ī different color temperature is set during night and daytime. If redshift doesn’t obtain the location from an automatic location provider then you need to specify your current location. ![]() This will reduce eye strain when you are working in computer at night or long hours.īy default redshift uses GeoClue to obtain your location (I mean, Latitude and Longitude of your location) to start. ![]() Redshift adjusts the color temperature of your screen according to your surroundings (position of the sun). To reduce or prevent eye related issues, I will advise you to use Redshift, It’s a nifty tool to reduce computer eye strain on Linux. We all knows, most of the electronic devices are emitting blue light which will impact our sleep badly, that too on night (after dark) but many of the people are working in night and long time at computer which leads to face so many eye related problems. ![]()
