===============================================================================
  DMS Greeter Installation Complete!
===============================================================================

Configuration status:
  - Greeter cache directory: /var/cache/dms-greeter (created with proper permissions)
  - SELinux contexts: Applied (if semanage available)
  - Greetd config: $CONFIG_STATUS

Next steps to enable the greeter:

1. IMPORTANT: Disable any existing display managers:
   sudo systemctl disable gdm sddm lightdm
   (Only greetd should run as the display manager)

2. Verify greetd configuration:
   Check /etc/greetd/config.toml contains:

   [default_session]
   user = "greeter"
   command = "/usr/bin/dms-greeter --command niri"

   (Also supported: hyprland, sway)
   Note: Existing config backed up to config.toml.backup-* if modified

3. Enable greetd service:
   sudo systemctl enable greetd

4. (Optional) Sync your user's theme with the greeter:
   sudo usermod -aG greeter YOUR_USERNAME
   # Then LOGOUT and LOGIN to apply group membership
   ln -sf ~/.config/DankMaterialShell/settings.json /var/cache/dms-greeter/settings.json
   ln -sf ~/.local/state/DankMaterialShell/session.json /var/cache/dms-greeter/session.json
   ln -sf ~/.cache/quickshell/dankshell/dms-colors.json /var/cache/dms-greeter/colors.json
