Hello,

I'm intending to use vnc to view a remote desktop from a RedHat server in an Ubuntu Work Station (WS). As my first alternative was the software the machines already have, I'm using "vncserver" and "vncviewer" produced by realvnc, I think. When I used that combination (i.e., vncserver / vncviewer) for the first time, the Ubuntu WS nicely displayed the
RedHat Server Desktop. After several tries, however, the WS isn't displaying the Desktop anymore: the only thing I get now is a black (or grey) window with an "X" cursor that moves as I move the mouse.
The details of the problem are as follows:

I started a vncserver in a RedHat Server with:
vncserver :11 -geometry 1000x700

The RedHat Server responded with
xauth: (stdin):1: bad display name "elcaos.imta.mx:11" in "add" command
New 'elcaos.imta.mx:11 (checo)' desktop is elcaos.imta.mx:11
Starting applications specified in /home/checo/.vnc/xstartup
The content of the xstartup file is:

#!/bin/sh

# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
export DESKTOP="GNOME"
exec /etc/X11/xinit/xinitrc
When I run the vnc client (vncviewer) in my Ubuntu Work Station the only thing I get is a black window, with an "X" cursor that moves as I move the mouse. The thing is that in the beginning the pair (vncserver / vncviewer) worked pretty well but now is just displaying this weird window.

Do you have any idea on what's happening?

Thanks

Sergio.
