Shadow on NixOS

⚠️ Since I canceled my subscription, I am no longer able to maintain this package. You may go to the following repository to get a functionning package: https://github.com/cornerman/shadow-nix

The goal of this project is to provide Shadow on NixOS with a dynamic derivation to handle frequent updates.

This project is not affiliated with Blade, the company providing Shadow, in any way.

1. Installation

Note that the ref value (v*.*.*) should point to the lastest release. Checkout the tags to know it. The version is the derivation one, not the launcher nor the streamer version. Installing any version of this repository will always install the latest version of the launcher available.

If you want the latest package derivation, use ref = "master" instead.

As a system package

In your configuration.nix :

{
  imports = [
    (fetchGit { url = "https://github.com/NicolasGuilloux/shadow-nix"; ref = "v1.0.3"; } + "/import/system.nix")
  ];

  programs.shadow-client = {
    # Enabled by default when using import
    # enable = true;
    channel = "prod";
  };
}

As a home-manager package

In your home.nix :

{
  imports = [
    (fetchGit { url = "https://github.com/NicolasGuilloux/shadow-nix"; ref = "v1.0.3"; } + "/import/home-manager.nix")
  ];

  programs.shadow-client = {
    # Enabled by default when using import
    # enable = true;
    channel = "preprod";
  };
}

2. Configuration

Package configuration

This is the configuration of the package itself. You can set them via programs.shadow-client.<key>.

Key	Type	Default	Possible values	Description
enable	bool	false	true, false	Enable the package
channel	enum	prod	prod, preprod, testing	prod is stable, preprod is beta, testing is alpha
extraChannels	[enum]	[]	[ "prod" "preprod" "testing" ]	prod is stable, preprod is beta, testing is alpha
launchArgs	string			Add launch arguments to the renderer
enableDesktopLauncher	bool	true	true, false	Creates a .desktop entry
enableDiagnostics	bool	false	true, false	Provide debug tools
forceDriver	enum	null	iHD, i965, radeon, radeonsi	Force the LIBVA driver
enableGpuFix	bool	true	true, false	Create the drirc file to fix some driver related issues

XSession configuration

This package also provides a standalone session with only the necessary component to start Openbox and Shadow. You can set the configuration via programs.shadow-client.x-session.<key>.

Key	Type	Default	Possible values	Description
enable	bool	false	true, false	Enable the standalone XSession
additionalMenuEntries		{}		Additional menu entries for the Openbox right click menu
startScript	string			Additional start option to be executed when Openbox starts

Systemd session configuration

This package provides a standalone systemd daemon to start only the client wrapped into Xorg in a TTY. You can set the configuration at programs.shadow-client.systemd-session.<key>.

Key	Type	Default	Possible values	Description
enable	bool	false	true, false	Enable the standalone XSession with Systemd
user	string			User that will start the session
tty	int	8		TTY number where the session will be started
onClosingTty	int	null		TTY number that will be selected on closing

3. About VAAPI

It is important to have vaapi enabled to make Shadow works correctly. You can find information on this NixOS wiki page.

An example for Intel and AMD GPU

The following example should work for both AMD and Intel GPU. This is just an example, there is no guarantee that it will work.

{
  # Provides the `vainfo` command
  environment.systemPackages = with pkgs; [ libva-utils ];

  # Hardware hybrid decoding
  nixpkgs.config.packageOverrides = pkgs: {
    vaapiIntel = pkgs.vaapiIntel.override { enableHybridCodec = true; };
  };

  # Hardware drivers
  hardware.opengl = {
    enable = true;
    extraPackages = with pkgs; [
      vaapiIntel
      vaapiVdpau
      libvdpau-va-gl
      intel-media-driver
    ];
  };
}

4. Versioning

shadow-nix follows semantic versioning. In short the scheme is MAJOR.MINOR.PATCH where

1. MAJOR is bumped when there is a breaking change,
2. MINOR is bumped when a new feature is added in a backward-compatible way,
3. PATCH is bumped when a bug is fixed in a backward-compatible way.

Versions bellow 1.0.0 are considered experimental and breaking changes may occur at any time.

5. Contributing

Contributions are welcomed! There are many ways to contribute, and we appreciate all of them. Here are some of the major ones:

• Bug Reports: While we strive for quality software, bugs can happen and we can't fix issues we're not aware of. So please report even if you're not sure about it or just want to ask a question. If anything the issue might indicate that the documentation can still be improved!
• Feature Request: You have a use case not covered by the current api? Want to suggest a change or add something? We'd be glad to read about it and start a discussion to try to find the best possible solution.
• Pull Request: Want to contribute code or documentation? We'd love that! If you need help to get started, GitHub as documentation on pull requests. We use the "fork and pull model" were contributors push changes to their personnal fork and then create pull requests to the main repository. Please make your pull requests against the master branch.

As a reminder, all contributors are expected to follow our Code of Conduct.
