Huh. I don't see how trying to install VNC with a DE (Desktop Environment) and WM (Window Manager) could break a VPS so much. There is something seriously gone wrong. I installed a DE with a WM on a VPS a few times together with x2Go (FreeNX) instead of VNC and never had such fatal failures.

I know that usually VNC itself gives trouble during such installations but not so far that the VPS is rendered broken or useless. VNC just won't work properly and give a grey screen when connecting or similar issues. Or the VNC server won't start because there is some error in the configuration. Similar VNC related issues that don't affect the other parts of the OS though.

If I were you I would investigate what happened. It is not normal that your VPS gets frozen when you install normal things like DE, WM and VNC. The guides I posted are totally fine and are the most common guides available. I mean I don't use VNC myself but I did as seach for you and the Linode guide with Gnome was available on so many sites with the content being a one to one copy of what was at the Linode article (I guess it is so good that people copy it to repost on their sites).
