NixOS/nixos-hardware

NixOS profiles to optimize settings for different hardware.

Setup

Using channels

Add and update nixos-hardware channel:

$ sudo nix-channel --add https://github.com/NixOS/nixos-hardware/archive/master.tar.gz nixos-hardware
$ sudo nix-channel --update

Then import an appropriate profile path from the table below. For example, to enable ThinkPad X220 profile, your imports in /etc/nixos/configuration.nix should look like:

imports = [
  <nixos-hardware/lenovo/thinkpad/x220>
  ./hardware-configuration.nix
];

New updates to the expressions here will be fetched when you update the channel.

Using nix flakes support

There is also experimental flake support. In your /etc/nixos/flake.nix add the following:

{
  description = "NixOS configuration with flakes";
  inputs.nixos-hardware.url = "github:NixOS/nixos-hardware/master";

  outputs = { self, nixpkgs, nixos-hardware }: {
    # replace <your-hostname> with your actual hostname
    nixosConfigurations.<your-hostname> = nixpkgs.lib.nixosSystem {
      # ...
      modules = [
        # ...
        # add your model from this list: https://github.com/NixOS/nixos-hardware/blob/master/flake.nix
        nixos-hardware.nixosModules.dell-xps-13-9380
      ];
    };
  };
}

Using fetchGit

You can fetch the git repository directly:

imports = [
  "${builtins.fetchGit { url = "https://github.com/NixOS/nixos-hardware.git"; }}/lenovo/thinkpad/x220"
];

Unlike the channel, this will update the git repository on a rebuild. However, you can easily pin to a particular revision if you desire more stability.
