Re: [gdm-list] GDM patch to make user switching able to pre-select user

[Brian Cameron <Brian Cameron Sun COM>]

Robert:

You can run ck-list-sessions to find out the mapping between sessions
and displays.  So, if you need to lookup what VT sessions the user may
already be using, I would think that you could get this information via
ck-list-sessions, or via D-Bus calls to access the ConsoleKit database
directly.
