I have activated VNC on our Linux-Server with the following /etc/xinetd.d/vnc Config-File

service vnc1
socket_type = stream
protocol = tcp
wait = no
user = nobody
server = /usr/bin/Xvnc
server_args = -noreset -inetd -once -query localhost -geometry 1600x970 -depth 16 -securitytypes none
port = 5901

When I am now starting two VNC-Sessions ("vncviewer <host>:1") and login with different user-id (e.g. "root" and "oracle") from a Windows 7 Client machine both VNC-Sessions working right. But, when I am trying to connect two times with the same user-id (e.g. "root") the second VNC-Session crashes and the VNC-Viewer closes without any comment. Under SuSE 11 it works right, starting two VNC-session with the same user-id is no problem.

Has anybody an idea how to fix the problems ?

Thx in advance.
