vnc experience

[Alex Troubadour]

Hi, All,
hopefully this is not too dumb a question.
On red hat enterprise 6, how do you set things so if you run vncserver on the server and do a vncviewer connection to it, you do not see a full graphical desktop ( with its menus, mozilla, etc. ) ?  I would like to have a "plain" background with a simple xterm ( from whcih you could call mozilla, etc. ).  It seems if I modify my xstartup I can remove my full-blown graphical desktop but then I have a blank vncviewer session and do not seem to be able to bring up an xterm window ... left, right, "center" clicking dowes not bring up a menu from which I can select "xterm" ... nor does it bring up any menu.  On older versions of red hat, I was successfully able to do so.  My xstartup file on that box was:
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &

Doing similarly on rh6 does not seem to work ( at least for me ) ... as I said, I do not seem to be able to bring up an xterm.
 
I tried installing twm ( "xorg-x11-twm-1.0.3-5.1.el6.x86_64" ) to no avail.
 
Thanks for any help you can provide.
