VNC viewer only can see xtern in remote desktop

[Barry Yu]

I have 2 machines, station-1 and station-2; both boot into fc1.
station-2 started the vncserver.
station-1 started the vncviewer, the result is - only can see the xterm 
of station-2, and a small vnc config box at left upper corner, the 
entire background is gray color, there is not control panel at bottom of 
window of station-2 !
So I reboot the station-2 and this time I select to boot into rh9 (Multi 
boot in this machine), and started the vncserver. Station-1(fc1) was on 
all the time without interrupt, and I started the vncviewer to connect 
to station-2 again, well! the desktop of station-2(rh9) is right there 
with my favorite wall paper!
Both machine running fc1 and the vnc could enable me see a terminal in 
remote desktop, need help to solve this problem. Thanks.
