Got it going with TwinView! Once I had one monitor working with the nvidia driver, I was able to sudo nvidia-settings to enable the second monitor, separate desktops. Saved that xorg.conf file. Then I went back into nvidia-settings and enabled TwinView. Saved a copy of that too. The only thing I had to manually add to the xorg.conf file was the ModulePath line that Michael helped me out with. I can send a copy of those conf files, if anyone wants a look-see. Now to revive my quest of getting MeetingMaker to work right in Wine on this box...
Good job! Actually, I wouldn't mind having a copy of your conf files. I may add a second monitor to mine and it would save some work. You can send them to my e-mail address.
Thanks, Michael
