# LXQt Default Greeter (SDDM with LXQt theme)
#
# This module configures SDDM as the display manager with LXQt theming
# to provide a consistent greeter experience for LXQt desktop environments.
#
# Features:
# - SDDM display manager with Wayland support
# - LXQt theme integration for the greeter
# - Proper session detection for LXQt-based environments
# - Qt theming consistency between greeter and desktop
#
# Usage:
# Add this to your host configuration instead of gdm.nix:
#   imports = lib.flatten [
#     # ... other imports ...
#     "hosts/common/optional/lxqt-greeter.nix"
#   ];
#
{pkgs, ...}: {
  # Enable SDDM as the display manager
  services.displayManager = {
    sddm = {
      enable = true;
      wayland = {
        enable = true;
        compositor = "kwin"; # Use KWin for the greeter compositor
      };
      # Use LXQt theme for SDDM
      theme = "breeze"; # Breeze theme works well with LXQt
    };
  };

  # Install SDDM themes and LXQt integration packages
  environment.systemPackages = with pkgs; [
    # SDDM themes that work well with LXQt
    kdePackages.sddm-kcm # SDDM configuration module

    # Additional SDDM themes (optional)
