CentOS 5 Server :: VNC - Black Screen - Missing Window Managers?

I have followed to the letter the wiki HowTo on setting up VNC and it works (sort of). I get a VNC session (doesn't matter whether I connect locally, over ssh, or using a vnc client), but all I get is the dreaded black screen with an xterm top left. If I then execute 'startkde' from within the xterm I get my normal desktop up. What I am however getting, is a new desktop session. And this happens each time I start a vnc session. I.e. I end up with a LOT of user sessions for my username. (As shown up by a 'users' cmd.) Consequently, each new time I start a vnc session, I get <x> (representing the previous nr of vnc logins) number of xterm windows + 1 appearing. I never get the logged on session.

However I've also noticed my .xsession-errors file filling up. I've googled around enough to get the impression that the reason I'm not getting the logged-on session up in vnc is due to a missing window manager. but haven't hit on the right google combo to fix the issue. I can believe there being a missing window manager due the following related story;About a year ago, I went to switch from KDE to Gnome. Decided I didn't want to and then set out to switch back to KDE. Each time I installed/uninstalled via the GUI "Add/Remove Software". Eventually I got back to KDE and it appeared to work since, so I left well enough alone.t is only now attempting to set up VNC, I have come across all these issues. I firmly believe VNC will work as expected if I can resove the apparent missing window manage issue.xstartup
