Installation

Quick Install

One-line installer that works on most Linux distributions:

curl -fsSL https://raw.githubusercontent.com/Nomadcxx/sysc-greet/master/install.sh | sudo bash

The installer automatically detects your package manager and works on Arch Linux, Debian/Ubuntu, Fedora, and openSUSE. It'll handle greeter backend selection, install dependencies, and set everything up for you.

Hyprland greeter support ends in ~3 months. New installs should choose niri (default) or cagebreak, its replacement.

Build from Source

If you want to build it yourself, just clone the repo and run the installer:

git clone https://github.com/Nomadcxx/sysc-greet
cd sysc-greet
go run ./cmd/installer/

The installer walks you through compositor selection and configuration.

Arch Linux (AUR)

Four AUR packages available depending on which greeter backend you're using:

# niri (default)
yay -S sysc-greet

# Cagebreak variant (the Hyprland replacement)
yay -S sysc-greet-cagebreak

# Sway variant
yay -S sysc-greet-sway

# Hyprland variant (deprecated, replaced by cagebreak)
yay -S sysc-greet-hyprland

The packages conflict with each other — install exactly one. sysc-greet-cagebreak pulls in cagebreak and socat from the AUR.

NixOS (Flake)

If you're on NixOS, add sysc-greet to your flake:

flake.nix:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    sysc-greet = {
      url = "github:Nomadcxx/sysc-greet";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { self, nixpkgs, sysc-greet, ... }: {
    nixosConfigurations.your-hostname = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        ./configuration.nix
        sysc-greet.nixosModules.default
      ];
    };
  };
}

configuration.nix:

{
  services.sysc-greet = {
    enable = true;
    compositor = "niri";  # or "cagebreak", "sway", "hyprland" (deprecated)
  };

  # Optional: Set initial session for auto-login
  services.sysc-greet.settings.initial_session = {
    command = "Hyprland";
    user = "your-username";
  };
}

By default, the NixOS module does not install niri, cagebreak, hyprland, or sway. Install your chosen backend yourself, or set niriPackage, cagebreakPackage, hyprlandPackage, or swayPackage if you want the module to install and use a specific package. If your compositor is managed elsewhere, set compositorCommand to the exact command greetd should run.

Then rebuild:

sudo nixos-rebuild switch --flake .#your-hostname

Note: On NixOS, sysc-greet automatically uses the correct data directory via build-time path injection. The Nix store path is injected at build time, so no manual configuration or symlinks are needed (in theory)
