Nix package set and NixOS module for using COSMIC from NixOS. This is a temporary repository for testing COSMIC on NixOS as it is developed. When COSMIC gets more stable and it is fully working on NixOS, these packages and module are intended to be merged upstream into nixpkgs.
If you have an existing configuration.nix, you can use the nixos-cosmic flake with the following:
{
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
nixos-cosmic = {
url = "github:lilyinstarlight/nixos-cosmic";
inputs.nixpkgs.follows = "nixpkgs";
};
};
outputs = { self, nixpkgs, nixos-cosmic }: {
nixosConfigurations = {
# NOTE: change "host" to your system's hostname
host = nixpkgs.lib.nixosSystem {
modules = [
{
nix.settings = {
substituters = [ "https://cosmic.cachix.org/" ];
trusted-public-keys = [ "cosmic.cachix.org-1:Dya9IyXD4xdBehWjrkPv6rtxpmMdRel02smYzA85dPE=" ];
};
}
nixos-cosmic.nixosModules.default
./configuration.nix
];
};
};
};
}After rebuilding with that configuration to get the binary cache substituters set up, enable COSMIC with services.desktopManager.cosmic.enable = true and services.displayManager.cosmic-greeter.enable = true in your NixOS configuration
