Wanted: login screen running under X for RS/6000

[Stacey Cherny]

Has anybody set up an RS/6000 console so that the X-server is
running at all times, with a login screen running under it?  That
sure would be a nice feature, since that way the X screen saver
could be running between login sessions.  If anybody has such a
setup, I would greatly appreciate knowing how it was done.  

Many thanks.
