Ditto here - both screens go blank in Unity if I try to enable external monitor from the Nvidia settings dialogue box.

I've also noticed that any windows that are minimised at the time I attempt to activate the second monitor won't restore when I click their Unity launcher icons or alt-tab once the display has returned back to normal. The top panel displays the name of the app, but the window itself doesn't appear. The only way around that seems to be to force-quit and re-open the program (or log out and back in).

If I enable twinview the same way under Xfce the twinview feature works perfectly.
