Default Nvidia and twin view - seems to work, but blank screen?

Hi all,
I ran into a problem this morning - after hooking up a secondary flat panel, and running nvidia-settings and configuring it for twinview - it seems as though it half worked.

My primary monitor still works, but the secondary monitor is blank, like it's getting no signal. Funny thing is that the desktop thinks it's there, because I can move my mouse over there into the blackness and then bring it back (as opposed to it hitting a "wall" on the other side of the monitor).

One thing I noticed, is that nvidia settings seems to think one of the monitors is a CRT, and the other is a DFP (both are Flat Panels), but they are mated to a DVI to dual VGA Y cable adapter.

My xorg.conf (well what's relevant I think):

Code:
Section "Monitor"
    Identifier     "Monitor[0]"
    VendorName     "--> VESA"
    ModelName      "1280X1024@60HZ"
