Well, you mentioned mythfontend, which may mean that this machine runs
MythTV, in which case you probably want separate X displays for each
monitor.  If that's *not* essential, then I think the fastest and
easiest way to fix your problem is to go back into the NVidia tool,
select "X Server Display Configuration" on the left, and then click
the "Configure..." button in the layout configuration dialog.  Choose
TwinView, make any other relevant changes, if any (I believe this will
be fairly intuitive), and restart X.  This will make your two devices
work like one big X display, and will still work fine if the TV is not
connected.

If that doesn't work for you, I think your best bet is to either
switch back to KDE (which I understand handles two distinct displays
better than GNOME), or switch to a non-"desktop environment" window
manager like FVWM.

I have a vague recollection that it's possible to run two instances of
gnome by somehow specifying an alternate location for the different
instances to look for their configuration info, but this memory is
probably eight years old, and highly unreliable. :)

If you want to stick with GNOME, and can't use TwinView, I'd suggest
posting on the gnome-users mailing list.  Someone there will know how
to do it, if it can be done...
