Redshift

Prerequisites

You can either manually configure a location or specify a location provider such as geoclue2 with the following options:

• location.provider
• location.latitude (Used by the manual provider.)
• location.longitude (Used by the manual provider.)

Installation

Install it with the redshift package. Example snippet of configuration.nix:

{ config, pkgs, callPackage, ... }: {
  environment.systemPackages = with pkgs; [
    ...
    redshift
  ];
  ...
  # All values except 'enable' are optional.
  services.redshift = {
    enable = true;
    brightness = {
      # Note the string values below.
      day = "1";
      night = "1";
    };
    temperature = {
      day = 5500;
      night = 3700;
    };
  };
};
