Hi Bill,
you are right. I've tried to start the last precompiled pymol 0.99rc6
X11 version for Mac with forced stereo and it didn't find the
capability for hardware stereo in Leopard's X11:
[dirk pymol]$ ./pymol -S
freeglut (/tmp/pymol/pymol.exe): ERROR: Internal error <Visual with
necessary capabilities not found> in function fgOpenWindow
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 4 (X_DestroyWindow)
Resource id in failed request: 0x0
Serial number of failed request: 18
Current serial number in output stream: 21
PyMOL: abrupt program termination.
Best regards,
Dirk.

Hi Dirk:
I think the X-11 hybrid is such that it uses an X-based TKinter gui
and non-X-based display window.
Try the fully X-11 fink pymol-py25 and see if that works in stereo.
If it does, we can try to fix coot. I don't have the stereo hardware
and probably will avoid it since CRTs and flickering lenses give me
migraines.

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:
http://xquartz.macosforge.org/downloads/X11_Legacy-1.1.4.1.pkg
Read the README, btw:
http://xquartz.macosforge.org/downloads/X11_Legacy.README
I'm not saying it will work, but I suspect it might.
--Jeremy
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.
