Solution #5: Edit the Redshift configuration file

Add the following lines to the redshift.conf file:


[redshift]
temp-day=15000
temp-night=3200
fade=1
location-provider=manual

[manual]
lat=52.3
lon=4.9

You can find the Redshift configuration file in the following location: /home/YourUsername/.config/redshift.conf. If the redshift.conf file is not there, you will have to create it.

You can open the Redshift configuration file using the following command:


sudo nano /home/YourUsername/.config/redshift.conf

The meaning of the lines in the Redshift configuration file:

  • temp-day is the color temperature for day time.
  • temp-night is the color temperature for night time.
  • fade is to make the transition between color temperatures smooth and not suddenly.
  • location-provider=manual allows us to enter our location manually so that Redshift will know the sunrise and sunset times by itself according to the latitude and longitude information we enter.
  • lat is the latitude of our location.
  • lon is the longitude of our location.

Steps

  1. Open a terminal window.
  2. Type (or copy and paste) the following command: 
    
sudo nano /home/YourUsername/.config/redshift.conf
  3. Press the Enter key on your keyboard.
  4. Enter your password.
  5. Press Enter.
  6. Add the following lines to the redshift.conf file: 
    
[redshift]
temp-day=15000
temp-night=3200
fade=1
location-provider=manual

[manual]
lat=52.3
lon=4.9
  7. Press the Ctrl + X keys on your keyboard.
  8. Press the Y key on your keyboard to save the changes.
  9. Press Enter.
  10. You can close the terminal window.
