I have a vps running Ubuntu server quantal (12.10) and have LXDE installed along with tightvnc. Well, I know there is something called openbox on there and I could install something else too. The problem is every time I connect to the VNC it is always LXDE that I see with no way of choosing what I want to interact with.

How do I change what the default GUI is going to be? I would assume that it is either a config that can easily just have a tweak or some command with a menu but I am having a hard time googling for the answer.

Can you help me?

Thanks
