[Bug 47005] Re: 'Switch User' button from 'System/Quit' should behave exactly like 'Switch User' from gnome-screensaver

[William Grant]

Hmm... I think the logout screen's Switch User functionality is the
right way, as the screensaver asks for a user to switch to, which is
then thrown away. There's no point asking for a username, as it just
throws you back to GDM anyway.
