Mr. Almighty Bbyer himself maintains our Xorg based X11 ports now ;-)
So maybe he can chime in and advise...?
In any case, I've been playing with X11 on Leopard lately but haven't
been able to experience this functionality, if I unset the DISPLAY
variable I simply can't open X11 programs from Terminal.app (even
Apple provided ones under /usr/X11/bin); no launchd magic happens and
all I get are "can't find display" errors (even though I do have a /
tmp/launch-QLJ9Yh/\:0 sockect). Guess I need to look into the matter
more thoroughly, I do have a highly customized environment after all.
Regardless, I'll add the corrections to our X11 advise on install.php
as soon as I get a chance.
Regards,...
