[FreeNX-kNX] Black Screen with Mouse Cursor After Successful Auth

[OwN-3m-All]

I am able to SSH using Putty with the old account just fine.  I just tried
the xterm command.  Freenx claimed to have established the display, but
then immediately crashed with nothing on my screen.  So, yes, I am able to
login locally to both gnome and terminal with that user account.  Freenx
just won't work anymore for that user since the crash, and I have no idea
why.  Also, for the new user I created, I am able to get in with freenx and
see a desktop, but my gnome windows are unmovable and fixed on the
screen?   I'm guessing I'll need to get X Windows and gnome working
properly before freenx works like it used to?  Surely someone has seen
something like this before though?

I've never seen a Linux machine pwn itself when rebooting until my server
crashed and messed this all up...
