OK, I've been debugging it quite a bit, and here's what I've found:

*I can SSH into my machine via a terminal by using: ssh localhost*
I'm able to get in fine, and I don't have any errors via the command line.
Is there something wrong with my freenx settings? Anyone know what's
going on? All help is appreciated.
