    ✓ Greeter user: Created
    ✓ Greeter directories: /var/cache/dms-greeter, /var/lib/greeter
    ✓ SELinux contexts: Applied

Next steps:

1. Enable the greeter:
     dms greeter enable

2. Sync your theme (optional):
     dms greeter sync

3. Check setup:
     dms greeter status

Ready to test? Run: sudo systemctl start greetd or reboot.
