    If you are ssh'ing in to run X, you can't do that. You want to log in via ssh
    launched from an X terminal on your local machine. Then in the ssh session
    execute the X app you want to run on the remote machine and it will be
    displayed locally.

    The X server can run lots of sessions at once, that's why it is a server :)
    There can only be one instance of a X server running per display (not the
    actual monitor), that is why you want to remove any old lock files that may
    have been created on any of the failed X startups (as your error message
    indicated).

    In X, the server is your local keyboard, mouse and video, while the client is
    the remote application. So when you run "xhost +" it should be on your local
    machine, to allow _any_ machine to display it's X application on your local
    machine. I don't think you'll need to do that though, as ssh should take care
    of X forwarding (which I beleive is on by default).

    Hope that helps.
