  I believe that the default X installation does not allow remote X
connections.  Here is the debconf message, which would have been displayed
if your debconf priority had been above medium:

 Because the X server runs with superuser privileges, by default it
 operates with TCP port listening disabled as a security measure.  This
 means that, as shipped, X servers started with xinit (or startx) are not
 reachable via the network and will refuse connections from X clients
 running on remote hosts.  (Outbound connections, such as those to X font
 servers, are not affected; neither are sessions tunneled or forwarded with
 ssh.)
 .
 Many people do not need to enable TCP port listening in their X servers;
 if you do, for instance to display remote X clients to your local X
 server, you can edit /etc/X11/xinit/xserverrc to remove the "-nolisten
 tcp" option.  Note that editing this file has no effect on X servers
 started with xdm or other display managers.
