[http://jonls.dk/redshift/ Redshift] is | [http://jonls.dk/redshift/ Redshift] is an open-source software application designed to adjust the color temperature of computer displays based on the time of day. Created by Jon Lund Steffensen, Redshift modifies the color temperature to reduce eye strain and improve sleep patterns. This application aims to provide a more comfortable viewing experience by dynamically changing the display's color temperature to match the user's surrounding light conditions. | ||
It does this by gradually shifting the color temperature of the display from cooler (bluer) tones during the day to warmer (redder) tones at night. | |||
Users have the flexibility to customize various settings in Redshift. They can specify custom values for day and night color temperatures, adjust the speed of color transitions, and temporarily disable or manually adjust the color temperature. | |||
== Installation == | |||
==== Using nix-shell ==== | |||
<syntaxhighlight lang="bash" start="3"> | |||
nix-shell -p redshift | |||
</syntaxhighlight> | |||
==== Using Global Configuration ==== | |||
<syntaxhighlight lang="text"> | |||
environment.systemPackages = [ | |||
pkgs.redshift | |||
]; | |||
</syntaxhighlight>After modifying your configuration, apply the changes by running:<syntaxhighlight lang="bash"> | |||
sudo nixos-rebuild switch | |||
</syntaxhighlight> | |||
==== Using Home Configuration ==== | |||
<syntaxhighlight lang="text"> | |||
home.packages = [ | |||
pkgs.redshift | |||
]; | |||
</syntaxhighlight>After updating your configuration, apply the changes by running:<syntaxhighlight lang="bash"> | |||
home-manager switch | |||
</syntaxhighlight> | |||
== Configuration == | |||
==== Basic ==== | |||
<syntaxHighlight lang=nix> | |||
services.redshift = { | |||
enable = true; | |||
temperature = { | |||
day = 5500; | |||
night = 3700; | |||
}; | |||
}; | |||
== | services.geoclue2.enable = true; | ||
location.provider = "geoclue2"; | |||
</syntaxHighlight> | |||
==== Advanced ==== | |||

# Display temperature settings | |||
# | temperature = { | ||

}; | }; | ||

}; | }; | ||
# Setting the location works either by using a provider | |||
services.geoclue2.enable = true; | |||
location.provider = "geoclue2"; | |||
# Or like this, which can also be set in services.redshift | |||
location.latitude = "27.9880614"; | |||
location.longitude = "86.92521"; | |||
</syntaxHighlight> | </syntaxHighlight> | ||
== | == Tips and Tricks == | ||
==== Location of Options ==== | |||
The home manager options are defined in the following [https://nix-community.github.io/home-manager/options.xhtml#opt-services.gammastep.enable Home Manager Options Manual]. | |||
The global options are listed on [https://mynixos.com/search?q=redshift MyNixOS]. | |||
==== Usage ==== | |||
<syntaxHighlight lang="shell"> | <syntaxHighlight lang="shell"> | ||
# 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 | systemctl --user start redshift | ||
Or permanantly enabled by creating the empty file | # Or permanantly enabled by creating the empty file | ||
~/.config/systemd/user/default.target.wants/redshift.service | ~/.config/systemd/user/default.target.wants/redshift.service | ||
After starting the service, make sure to check its status in the service manager: | # After starting the service, make sure to check its status in the service manager: | ||
systemctl --user status redshift | systemctl --user status redshift | ||
</syntaxHighlight> | </syntaxHighlight> | ||
== Troubleshooting == | |||
==== Provider is unable to determine location ==== | |||
It may happen that redshift gets stuck at ''"Waiting for initial location to become available..."'' when using the {{Ic|geoclue2}} location provider. This may happen when geoclue is unable to determine your location due to missing information. In that case, you may resort to setting the location manually. | It may happen that redshift gets stuck at ''"Waiting for initial location to become available..."'' when using the {{Ic|geoclue2}} location provider.
