Speeding and Compressing X forwarding Traffic

To run the an X application over SSH connection, you can use the 
$ ssh -X user@computername.com

Do note that for the remote Server shich you are connecting to must have X forwarding enabled. To configure, go to /etc/ssh/ssh_config/
X11Forwarding yes

If the SSH is setup with trusted X11 Forwarding ie in the /etc/ssh/ssh_config file,
ForwardX11Trusted yes

You can compress and speed up the X forwarded connection
$ ssh -Y -C user@computername.com
  • -Y to enable trusted X11 forwarding. Trusted X11 forwardings are not subjected to the X11 SECURITY extension controls. So it will boost speed.
  • -C to compress the data
