Correct, there is additional configuration you need to do.
vncserver is to Xvnc what startx is to X.
VNCServer is just a virtual X server, so if you want anything like, say,
oh, a window manager or desktop, you need to start it. One problem is
that some desktops/window/display managers assume you are starting them
under root (gdm is one). Others, like fvwm2, don't care. Fortunately
there's a "hook" to let you start whatever you wish, called xstartup.
Create a file "~/.vnc/xstartup". This is run by vncserver at startup.
You can put whatever things you want to run in it.
Here's mine:
-----------------------------------------------------------------------------
#!/bin/sh
exec /etc/X11/xinit/xinitrc &
-----------------------------------------------------------------------------
Then do a chmod a+rx ~/.vnc/xstartup
xinitrc is a standard X startup script and is what xinit runs. xinit is
what startx runs to start the normal X server. xinitrc looks for
~/.Xclients or /etc/X11/xinit/Xclients to start things up. ~/.Xclients
is for those people who want to control exactly what gets started.
/etc/X11/xinit/Xclients runs the desktop defined in /etc/sysconfig/desktop.
I'm not a fan of KDE or Gnome (at least not yet :-), so I installed fvwm2
from the Tasty Morsels CD and created my own ~/.Xclients:
-----------------------------------------------------------------------------
#!/bin/sh
rm -f $HOME/Xrootenv.0
rm -f /tmp/fvwmrc* 2>/dev/null
xsetroot -solid SteelBlue
xhost + > /dev/null 2>&1
fvwm2 &
-----------------------------------------------------------------------------
