I'll go ahead and close out this bug report since the original issue is resolved and we like to keep one issue per bug report. :-)
The screen corruption is a unity-greeter bug. Known issue, and not driver-specific.
As to the error dialog, I think that is GNOME not Xorg. Try deleting your ~/.config/monitors.xml. GNOME is probably not recognizing that the nvidia driver is setting up the modes in this case. If that doesn't solve it, file a bug against gnome-settings-daemon.
