xhost + is not a good idea...

For example:


Have you tried

ssh -X you at your-server   ?

man 1 ssh

 -X      Enables X11 forwarding.  This can also be specified on a per-host
             basis in a configuration file.

Is X forwarding enabled ?

$ grep -i forward /etc/ssh/sshd_config 
X11Forwarding yes
