basic mosaic disables 2nd monitor with nvidia binary driver and gnome

I am not sure exactly when this issue was introduced but recently when specifying the basic mosaic option in nvidia-settings causes xorg to disable the secondary monitor you attempt to put in the mosaic leaving you with only one functioning monitor. Nvidia-settings was run as root below is a cat of my /etc/X11/xorg.conf

cat /etc/X11/xorg.conf
