Hi,
I am using OpenSSH on a 4.0-stable box.
The manpage states:
The session terminates when the command or shell in on the remote machine
exists and all X11 and TCP/IP connections have been closed. The exit
status of the remote program is returned as the exit status of ssh.
If the user is using X11 (the DISPLAY environment variable is set), the
connection to the X11 display is automatically forwarded to the remote
side in such a way that any X11 programs started from the shell (or com-
mand) will go through the encrypted channel, and the connection to the
real X server will be made from the local machine. The user should not
manually set DISPLAY. Forwarding of X11 connections can be configured on
the command line or in configuration files.
The DISPLAY value set by ssh will point to the server machine, but with a
display number greater than zero. This is normal, and happens because
ssh creates a ``proxy'' X server on the server machine for forwarding the
connections over the encrypted channel.
However, the DISPLAY variable does not get set when I connect to a
remote machine (running ssh but not OpenSSH). Here is an example
session:
r.arthur ~ % echo $DISPLAY
:0.0
r.arthur ~ % ssh -V
SSH Version OpenSSH-1.2.2, protocol version 1.5.
Compiled with SSL.
r.arthur ~ % ssh -l jesse knecht

Am I just missing some config setting or does it simply not work?
