[rhelv6-list] vnc how to get gnome session login?

[Alois Treindl]

I am tryiong to configure vnc on a new RHEL6 system.

Like on RHEL 5 systems I adminster I set it up as a service via xinetd.

My xinetd.d entry /etc/xinetd.d/vnc says
service vnc
{
         disable = no
         socket_type = stream
         protocol = tcp
         group = tty
         wait = no
         user = nobody
         server = /usr/bin/Xvnc
         server_args = -inetd :2 -query localhost -geometry 1200x900 
-depth 16  -fp /usr/share/X11/fonts/misc/ -securitytypes=none
         flags           = REUSE
}

and in /etc/services I define service vnc as
vnc           5901/tcp

When I connect to the vnc service, I get a black empty x11 root window, 
but nothing visible on it.

What I would like to get is a gnome login

On my RHEL5 systems where I have basically the same setup but also a 
confuration for xdmcp for X-terminals I get a login screen for a full 
gnome session with vnc.

What do I have to do to get the same on RHEL 6 ?
