Re: [gdm-list] double login

[Brian Cameron <Brian Cameron Sun COM>]

Guy:

Glad to hear that you found some solution.  When
AlwaysLoginCurrentSession is true, this causes GDM to reconnect to any
running VT session.  So if you have a session running on VT7 and you try
to log into the same user on VT9, it will just switch you back to VT7.
The "double login" warning is a VT-specific feature, so it is expected
that you wouldn't see the warning when users try to login twice in
non-VT environments (such as multiseat or terminal server environments).

Note that VT switching is only useful on the console display and is,
therefore, generally not supported in multiseat environments.  If the
version of GDM you are using is not smart enough to realize that
non-console displays do not support VT, then it makes sense to disable
VT.  Setting VTallocation to false basically turns off VT support
entirely in GDM.

You are using GDM 2.18?  If you want to continue using the "old GDM", 
then you might considering updating to the latest 2.20.10 version.  A
lot of bugs have been fixed in 2.20.10, so you might find it works
better.
