I dunno, but I do know I have to use nVidia's configuration app, after 
loading the driver, to turn on twinview support. It sounds like you have 
one monitor as mirror to the other primary one?

Now that I have three monitors with two identical nVidia cards, I have 
to use xinerama to run all three screens as one desktop window. That 
does seem to incur a performance hit.

Without having some sort of driver supported app, I would suggest you 
google on xrandr as that might actually be a better way to go. I'm 
looking into that myself. There are several gui's for xrandr in the 
repos. I tried one but it didn't get there for me. Not yet. YMMV, Ric
