That's almost what I meant. If DISPLAY is set, it should try

I believe maps to the same thing), try the launchd socket. Again,
it has to be
able to tell what it was first.
That way, it would work even if the user had set DISPLAY to unix:0
or :0 in
their .profile or wherever. You would *not* want to just treat all
DISPLAY
strings that map to a local connection as the launchd socket
because that would
preclude somebody trying to run a *different* X server.
Somebody also pointed out that localhost:0 means the local display
but using
TCP/IP protocol instead of Unix sockets. If X11 is already
running, then
attempting to connect to localhost:0 would just work. If it's not
running, that
would fail (probably after a few seconds timeout on the socket
connection).
In that case, libX11 could connect once through the launchd socket
to get X11
up and then try localhost:0 again for the "real" connection. This
would make
your client take longer to launch using "localhost:0" if X11 isn't
running than it
would using ":0", but if you're just using "localhost:0" to test GL
vs GLX, you
probably fall under the category of people who keep X11 running all
the time
anyway and would never notice :-)
