It doesn't sound like a problem with ssh to me, it sounds like you
haven't set the DISPLAY variable correctly, and therefore probably
haven't run xhost either.

desk.host: # xhost +remove.host.domain.com
desk.host: # ssh -X remote.host.domain.com -l myaccount
myaccount@remote.host.domain.com's password: ********
remote.host: # export DISPLAY=desk.host:0.0
remote.host: # xterm &

That should do it.

Mind you, DISPLAY seems to get set correctly on my box automagically,
but I don't know how it goes about that.
