I'm running Ubuntu on my desktop and am trying to interface with a server running CentOS. So far I've been connecting using PuTTY, which has worked just fine, however I've reached a point at which I need to utilize a GUI for some data visualization (an application called PAVE). I know that PuTTY allows you to enable X11 forwarding, but when I enter "startx", it won't launch due to an "AttributeError".

Although it may not fall within the scope of a Ubuntu forum, I figured it was worth asking. Any insight or advice on this problem would be greatly appreciated.
