The way to uninstall the legacy X11 package is just:
1) Install the latest 2.2.0.1 from xquartz.macosforge.org
or
2) sudo rm -rf /usr/X11R6 && sudo ln -s X11 /usr/X11R6
sudo pkgutil --forget org.x.X11_Legacy.pkg
Sorry this wasn't clear to you =(
I updated the README.

Dear X11 users,
here is summary of what I tried under Leopard:

FWIW, You might want to try the legacy ("Tiger") version of X11 for
Leopard:

Read the README, btw:

I'm not saying it will work, but I suspect it might.

installation went fine, but X11 applications could not be closed
properly (as Jeremy described in this thread). In one graphics
application the mouse behaved erroneously, the other application
resulted in a bus error, I even couldn't try X11 stereo. So, this
version was not useful. Strangely, I could not succeed to revert to
Leopard's X11, even when I removed all X11-related stuff and re-
installed X11 from the optional installs on Leopard's installation
DVD. After fiddling around a couple of hours, I decided to re-
install Leopard which was much faster.
I then followed Ben Byer's "easier instructions to install Tiger's
X11.app": http://lists.apple.com/archives/x11-users/2007/Nov/msg00005.html
Same observation as with the legacy X11 package. But this time, I
could easily revert to Leopard's X11 following his instructions.
I found one application that runs in X11 stereo on Leopard (!),
namely PyMOL (www.pymol.org). It comes in two flavors, an Aqua-
version MacPyMOL without X11, and an X11 version that you can get by
copying MacPyMOL.app to PyMOLX11Hybrid.app. Starting
PyMOLX11Hybrid.app in a terminal with forced quadbuffered stereo
give as command line option "-S" results in an X11 graphical
application that really runs in hardware stereo mode using Leopard's
X11! So, apparently, Leopard's X11 _is_ already stereo-capable, but
it simply doesn't report this to applications that somehow query for
stereo-capability! Maybe, this is an easier fix, than thought?
Best regards,
Dirk Kostrewa.

Dear X11 developers,
this is not a bug report but my personal view how important a
working X11 stereo on Leopard would be. Most of the scientific
graphics programs that support hardware (or quadbuffered or
sequential) stereo display via an emitter and stereo glasses use
X11 for that purpose. These programs worked well in stereo with X11
on Tiger, but fail with X11 on Leopard. Asking the developers of
these programs why X11 stereo on Leopard fails usually results in
the rather helpless reply that Leopard's X11 doesn't report its
stereo capability to their programs. In a scientific environment,
X11 stereo is one of the most important features if you work with
complicated 3D objects like big protein or DNA structures. The non-
functional X11 stereo in Leopard creates a lot of headaches amongst
scientific software developers and users that have to use X11
stereo, and keeps me from upgrading to Leopard on my MacPro.
May I express my urgent wish, probably also in the name of my Mac-
using colleagues world-wide, to get a working X11 stereo on Leopard
as soon as possible?
Many thanks to all X11 developers who have addressed and corrected
so many bugs in X11, thus far!
Best regards,
Dirk Kostrewa.
