Hi there, Dave!

There are some things you need to verify, mainly that your SSH X tunneling 
is enabled on both the remote server and your client.

Two variables in the server config need to be set:

  X11Forwarding yes
  X11DisplayOffset 10

The last one isn't really needed, but it's default, you can set it to 
whatever you want.

For the client config, the following variable needs to be set:

  ForwardX11 yes

which is default, so it should work without it entirely.

Now, it said "unable to open display :0.0" which is odd for X tunneling 
since default X display offset is 10. If the above mentioned settings are
correct you should find that your DISPLAY variable is set to :10 which is
the virtual X display.

Hope this sets you in the right direction.

/Peter
