Re: [gdm-list] multiseat disable multiple logins

[Brian Cameron <Brian Cameron Sun COM>]

Guy:

The only other configuration option which affects this is
AlwaysLoginCurrentSession.  You might try changing that value to true.
However, on non-migratable desktops, this wouldn't have an effect.
I guess a new configuration option to disallow users could be added.

Or, perhaps you could hack the Xsession script so that it checks if
the user is already running a session, pops-up a dialog letting them
know of the answer and when they click the "OK" button, and exits
without starting another session.

This is a bit hacky, but should meet your need using existing interfaces.
Or perhaps see if you can fix your Xserver so the problem goes away.
