Which is not working, xhost + or ssh -X?  They are very different.

With xhost + you set your remote DISPLAY to something like 
localmachine:0 (the :0 is the local X server).  Then the window is sent 
from the remote machine.  You have to tell your local X server to accept 
remote clients (listen on port 6000 or something).  You can google for 
how that is enabled (since it isn't secure it is disabled in modern 
configurations).

With ssh -X, ssh sets the remote DISPLAY to something like 
localhost:10.0 and listens for connections on port 6010.  Any 
connections to that port (on the remote machine) get sent back to the 
local machine where ssh displays them for you.

After you ssh, echo $DISPLAY.  If it isn't set, fix the settings in 
/etc/ssh/sshd_config.
