You just make a:
xhost +name-of-your-lispm
and a:
rsh name-of-your-lispm start X screen name-of-the-X-server
et voila, you have a Lisp machine console on your X server.

I have been able to run everything except Zmail. (but keep in mind that only
one user is login at the same time on the X client (or Genera server))

Everything "cleanly" written works without any problem. If you use
dw:define-program-framework, your stuff will probably work right away.

I have run the Genera X client on 3600, Ivory 1, and I must say that I am
impressed. On all these machines, the X client is fairly fast. I do not have
any hard numbers, but my feeling is that it is 10-20% slower than the console.

To take full advantage of the X server, make sure that it has direct access to
the Genera fonts.

The X server on Genera is really slow... but as I said earlier, the X client is
really nice. I have been using it for a while now, and really like it.
