    Hello All,

    Using X11Forwarding on the server, and ssh -X on the client,
    how do I get an x app to display over the wire after su'ing
    to another user?

    Is this a configuration issue, or limitation of the Xsession?

    Thanks for your time!

    [foobar@server]$ su

    X connection to server:11.0 broken (explicit kill or server shutdown).
