It is a very nifty thing one enables but may have a huge impact on one of the most precious parts in his/her body: The eyes.

screen=0 is to tell Redshift which monitor we want to apply the night light on (counting starts from 0).

lon is our current location’s longitude.

lat is our current location’s latitude.

location-provider=manual this is to tell Redshift that we want to enter our current location manually, so that the software later can know the sunrise and sunset times by itself according to the latitude and longitude information we enter.

fade is just to make the change from one temperature to another (when it happens) gradual and not sudden.

temp-night is the color temperature required for the display in the night time.

temp-day is the color temperature required for the display in the day time.

Let’s start explaining each line in the Redshift configuration file: You have to open the file at the /home//.config/nf (or create it if it doesn’t exist), and place the following contents inside it: Getting Night Light on Linux with Redshift Installing Redshiftįor Debian, Ubuntu, or other Linux distributions based on any of them, simply run the following commands in the terminal in order to install the software: sudo apt install redshift redshift-gtkįor other distributions, just search for the redshift package in your package repositories and install it.
