Probably your ssh (and sshd) is already configured to do X forwarding.
(That is what I do by default with some remote systems. This reminds me
that I want to try some of those new X compression or other techniques for
speeding up X.)

If you want your prompt back then background the command with an ampersand
"&" at the end of the line.

It does not need to be on local machine too. (The local machine is the X
server; the remote machine is running your applications which are called X
clients.)
