Mirror displays on Mint 15 login screen

Mirror displays on Mint 15 login screen References I have the Mirror Displays enabled on my Linux Mint 15 (Cinnamon, 64-bit) box and a GTX 680 graphics card. However, when on the login screen, the display is not mirrored; it\'s displayed on the primary monitor only. I really would like to have the WebGL clouds MDM login screen projected on a 108″ screen. Is there any way I could do this?
