Why it exists
Multi-monitor users often see the login screen use a different primary monitor, orientation, or arrangement than the desktop session. ddm-sync copies the layout you already configured to the display manager.

About
ddm-sync is a small Linux desktop utility for fixing mismatches between multi-monitor desktop layouts and login-screen layouts.
Design boundary
It does not manage monitor settings itself. It copies the existing configuration to the location expected by the login screen.
