I've got SSH access, and I have Xming installed, along with Xming fonts. I've configured putty to forward x11 and told it to place the desktop at localhost:0, according to the instructions here.

However, after I log in, and startx, I get ... Nothing. Or rather, it runs a but of messages which appear to say everything's working, but I get a cursor in my console window which acts like it in a wait state. And that's it.

What am I missing? Do I need to open something to see the desktop?

I want to forward my desktop to my work PC, so that I can play with RasPi at lunch, without physically plugging in the hardware. Please help.
