The ssh client doesn't forward X connections by default because doing so
opens you up to attacks by anyone controlling the server, and you should
be sure that you trust the server before doing this. I'm quite surprised
that Red Hat leave this setting on by default; I'd consider it a major
bug.

You can use 'ssh -X <host>' to enable it on a case-by-case basis.
