Redshift [http://jonls.dk/redshift/ project page] is a program that adjusts the color temperature of your screen according to your surroundings. By reducing the amount of blue light emitted it may help to reduce strain on the eyes if working in front of the screen at night. It's functionality is similar to f.lux. | |||

To properly work, Redshift needs your location to know when the sun will be setting and it gets dark outside, so that it can automatically adjust your screen temperature accordingly. | |||
You can either manually configure a location or specify a location provider such as geoclue2 with the following options: | You can either manually configure a location or specify a location provider such as geoclue2 with the following options: | ||

After starting the service, make sure to check its status in the service manager: | |||
<syntaxHighlight lang="shell"> | |||
systemctl --user status redshift | |||

It may happen that redshift gets stuck at ''"Waiting for initial location to become available..."'' when using the {{Ic|geoclue2}} location provider. This may happen when geoclue is unable to determine your location due to missing information. In that case, you may resort to setting the location manually. | |||
