Separate x-screens option does not result in a desktop manager on the 2nd screen
In a dual monitor setup, using the nvidia driver 'current' (because 173 won't even allow for settings to be changed), the Separate X Screens option results in a desktop on one (the main) screen, and the other screen with a blank white background and the default X cursor.
Enabling Xinerama in this same configuration results in a X session that freezes shortly after login.
