I was able to run a vncserver and connect to it without a problem. After
switching to xfce from kde, viewer connects but all I get is a blank

I am running the server on a Kubuntu machine. I tried connecting to it
via TightVNC from a Windows machine as well as via vncviewer to
localhost from the Linux server itself.

When I run the server I get the following log:

When I connect from the client using vncviewer, this additional message
is received:

I don't know how to debug it and logs do not tell much. Does anybody
have any idea what would be the cause?

Thanks...

sounds like your not starting a xfce session manager if you want to run
xfce. Do you have:

/usr/bin/xfce4-session
in your xstartup and does
ps -aef | grep xfce
show some xfce processes running after you start your vncserver?

Thank you Jack. Where is the "xstartup" file located? Do I need to
manually edit it to run the x-session?

On my Fedora install, when you start vncserver for the first time,
it creates a ~/.vnc directory with a xstartup script in it.
I changed my xstartup scrript to do:

#!/bin/sh

# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc

/usr/bin/xfce4-session &
wait


so when vncserver starts, it starts an X session and the
xstartup script starts my xfce4-session manager.
