This is my first post to the list, so I guess a "hello, world" is in order.
I figured it was time to get serious about PyMOL given that it's the first
application I've been able to get to work with Hardware Stereo on a linux
box:
* (6/10/2002) Hardware Stereo 3D under Linux! I have personally
confirmed that PyMOL performs well with quad-buffer hardware
stereo under Linux. Thus, I can now recommend the following
configuration, which also works well with the absolute latest
version of O (8.0.8):
+ Linux RedHat 7.1
+ ATI FireGL2 (unfortunately expensive, and now special-order
only).
+ Exact drivers: fgl23glk-glc22-4.0.3-1.9.7.i586.rpm +
fgl23ddx-glc22-4.0.3-1.9.7.i586.rpm

egl4certx403197.html
Other versions may work, but these are the only RPMs which
functioned in my hands.
+ Affordable emitters and glasses can be found at
www.nuvision3d.com.
+ An untested graphics alternative would be to use a Radeon
8500 card with the XIG driver and a suitable emitter adapter.
I can confirm that PyMOL 0.83 running atop Mandrake 8.1, with a 3DLabs
Oxygen GVX1 video card and the the XIG Platinum WX driver can render
hardware stereo just fine. We're using the McNaughton (eg, NuVision) stereo
glasses. The box has dual PIII 500MHz processors on an intel 440BX chipset,
with 512MB of memory.As our test case last week, we were looking at the PDB
file 1FJG, a structure of a 30S ribosomal subunit (a pretty beefy file).
I had to uninstall (rpm -e) XFree86-devel and dependency-related packages,
and had to install the XIG X server rpm with --nodeps, and had to fiddle
with some font path settings (with which XIG provided prompt and useful
help).
I also have a Radeon 8500 I'll be testing either in the next day or two, or
in a couple of weeks. A lot of our systems have video cards with nVidia
chipsets in them, which I guess we'll have to replace unless nVidia gets
around to supporting hardware stereo in their driver set before that
happens.
So far, a rewarding experience.
Now, I get to look forward to learning how to put PyMOL through its paces
(I'm a longtime MOLMOL user)!
