Revision as of 08:48, 3 August 2020

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

Enable services.redshift. Example snippet of configuration.nix:

  ...
{ config, pkgs, callPackage, ... }: {
  ...
  # 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;
    };
  };
};

Usage

If services.redshift.enable is true, the systemd unit redshift.service is provided. It can either be started by the user level service manager like this:

systemctl --user start redshift

Or permanantly enabled by creating an empty file at

~/.config/systemd/user/default.target.wants/redshift.service
