And, really, using "ssh -Y", as Ian suggests, is better than using "ssh
-X"--unless, of course, you suspect that the program you're executing
may be logging keystrokes or stealing clipboard data or something.  (I
haven't yet found the code in Myth that does this, so I use "ssh -Y" for
it.  Granted, I can't check nvidia-settings's code, but I'd probably
trust it as much over ssh as I would when running it locally.)
