OpenSUSE Network :: Unable KDE With VNC Connection?

I'm trying to enable a VNC connection from a Windows machine to remotely connect into my openSUSE machine (11.2, KDE, 64-bit), but I cannot get any desktop environment to load up at all. It just comes up with a blank screen and a black cross for a cursor. What I want is to be able to see exactly what I would normally see if I were sitting in front of it, rather than go into a 'virtual desktop' as appears to be the case. Ideally I would want to go into the KDE desktop environment in this instance, and it would also be nice if dual monitors could enabled for each remote session. How do I go about enabling my chosen environment?

If it makes any difference at all (although I doubt it does), I'm also using PuTTY in Windows in order to make an SSH tunnel to allow secure access, and I'm quite sure I've enabled all the necessary services for all of the above under the YaST Firewall (by the way, on a lesser note, do I need PuTTY to be installed at both ends for the SSH tunnel to work properly?). If you need a screenshot or output from terminal of sorts this can be arranged.
