If I swich users via system/exit/switch-user to an already active user, the sequence of events is this:
* gdm asks for the user
* gdm asks for the password
* gdm asks me (in an unclear language) whether to
launch a new session or go back to the previous.
* I choose to go back to the previous session
* I get a black screen
* I move the mouse
* I get the gnome-screensaver password check dialog.
* I type the password again.
* I enter the session.
Gnome-screensaver should not be active the moment I switch users. After clicking on entering previous session, I should directly enter that session.
