Well, actually, running it from an xterm essentially ensures that the X
server is running -- as long as DISPLAY is set properly (and it usually is
in an xterm), there should be little difference between running ssh from
an xterm or from a console shell. Unless... Make sure you're running a
Cygwin ssh client, or it may not react nicely to ptys (Cygwin's
implementation of ttys) that xterm uses.
Do try running ssh with -x, though, just to confirm that the problem is
indeed with X forwarding, and not generally with ssh.
