Bug Description

If I start the computer, and choose a unity session, I can't switch users.

When I try to use the menu to select a new user, the screen goes blank. If I touch the mouse, it just shows the locked screen for the current user.

By contrast, If I choose a gnome session to begin with, I can switch users. However, if the new user starts a unity session, they also won't be able to use the menu on the top right of unity, to switch back to the other session.

I am using GDM and Quantal.

There was an ubuntu patch that enabled fast user switching on ubuntu in gdm 3.0, however this patch has not been ported to gdm 3.6.

gdm has dropped gdmflexiserver, which is why there is no "switch user" button on the gnome-screensaver login dialog.

Closing gnome-screensaver task - we'll go with your solution Tim and revisit this next cycle as GNOME does too.
