What is Redshift?
Redshift adjusts the color temperature according to the position of the sun. A different color temperature is set during night and daytime.
During twilight and early morning, the color temperature transitions smoothly from night to daytime temperature to allow your eyes to slowly adapt. At night the color temperature should be set to match the lamps in your room. This is typically a low temperature at around 3000K-4000K. During the day, the color temperature should match the light from outside, typically around 5500K-6500K. The light has a higher temperature on an overcast day.

$ sudo apt install redshiftworked for me out the box.$ nohup redshift &was able to start and then shut down terminal. Have yet to add to startup applications with lon and lat. Otherwise works with Nvidia GPU where flu.x did not.It actually does what it promises to do. It's very simple, just install it with apt or .deb files or even the source and then it's ready. I installed it by apt and I didn't need to do anything else. It automatically sets the right settings for me. No more bright glowing screens in the night.

I've tried to get this running on Windows 10 1903. I've created a "redshift.conf" in the same directory and in "%UserProfile%\.config", it still said, that I should provide lat/lon. Starting it with ".\redshift.exe -l 48.1:11.6" it said, that it failed to use the method wingdi (Windows GDI). No other methods are provided. Even after running it with elevated rights, it failed. A huge waste of time.

couldn't get it to work with Windows unfortunately.
Small note for Windows users, you need to use the
-m wingdiparameter or else you will get an errorUnknown adjustment method 'randr'.I've also created a gist here on setting up redshift to run automatically and silently on startup: https://gist.github.com/dowodenum/2bfc9865a57c82fe45aad8ca5561382c#file-redshift-exe-startup-wrappers-for-windows
