Description darkxst 2012-09-27 02:49:43 UTC 
On a single user, Multi Session system. Clicking on "Switch Session" in the user Menu, just drops to the lock screen (i.e. you get exactly the same result as you do when you click "Lock" in the user Menu) and no way to actually switch session.

Comment 2 darkxst 2012-09-27 04:12:43 UTC 
On a Multi-user setup, "Switch User" only works the first time, after that it
also drops straight to the lock screen, rather than the switch user greeter.

Is this a systemd system ?

If so, can you show the output of loginctl list-sessions and loginctl session-status for the gdm and user sessions ? I think what might be happening here is that the gdm session lingers around on the same vt as your user session, so when you initiate user switching, gdm activates the ghost gdm session on the same vt.

libdgm: correct invalid g_variant format string

User switching is broken on consoleKit systems where there is an active
login session. This is due to this invalid g_variant format specifier.

I am on a console Kit system.

That patch fixes the problem of dropping to lock screen rather than the gdm login screen.

However "Switch Session" on a single user, multi Session system is still flawed. What happens now is, clicking 'switch user' takes you to the gdm login screen, then click on the username and you login back to the previous session where you started.

The 'switch session' problem is something else: bug 685062
