Yeah I tried that and I get
Error: Can't open display:
going from Tiger to Tiger with stock settings and no DISPLAY set.

You should not set DISPLAY. When you connect with ssh, just use
the -Y flag and your DISPLAY will automatically be set on the
remote host. Do not use "xhost +remotehost", that's a security hole.

Opps I'm sorry. . . . I got that a little backwards. .
The scenario below does work.
The scenario I was thinking about is ssh from Tiger to Tiger once
you remove DISPLAY to accomodate Leopard. I had DISPLAY exported
in /etc/bashrc for all my Tiger installs. . . but Leopard
obviously doesn't play well with that.
So now I remove that to accommodate Leopard's X. . . but now when
I ssh Tiger to Tiger. . .obviously there is no DISPLAY being
passed. So I guess now I have to manually set DISPLAY every time I
ssh from Tiger to Tiger if I've removed DISPLAY to accommodate
Leopard's new X11?

It should not affect that situation, should it? I mean ssh (with
tunneling, which I assume you mean) sets your DISPLAY for you
automatically. You should probably not override that, unless you
are using xauth or something. So just leave it alone and it
should work.

Speaking of strange things. . .
What is the "recommended" way for X DISPLAY to be handled
between Leopard and Tiger?
Obviously since Tiger needs it set. . . and Leopard does
not. . . and if Tiger HAS it set and you SSH to it from a
Leopard box (I.E. laptop) there is no X forwarding magic
happening there.
(An no the answer shouldn't be upgrade your Tiger installation
to Leopard ;) )
Thanks,

I was one of the people having problems starting X due to my

being set (thus preventing the magic launchd smoke and mirrors

string from being used). After hunting through my dot files, I
finally realized that I was setting it in ~/MacOSX/
environment.plist.
I think I was doing that because it got me a DISPLAY in
terminal, but
I honestly don't remember. Removing it, logging out, and
logging in
again allowed X to work normally. (if you can consider the
strange
launchd behavior normall..)
Where by "strange" you mean "carefully designed and improved",
right?
