the same thing with OpenSuSE 11.2 and couldn't get it to
work at all. The reason, at least how I got it after a long,
long discussion with custhelp.nvidia appears to be that some
distributions mount USB devices under /proc/bus/usb/devices
(works...) and some under /dev/bus/usb (doesn't work). In
OpenSuSE, which belongs to the latter class, the driver
appears to look under the non existing
/proc/bus/usb/devices, doesn't find the entry for the
3D-Vision emitter and refuses to switch on stereo. The
nvidia guys tested it with RHEL 5, which belongs to the
former class of distributions. Unfortunately the USB Emitter
must be recognized for reasons I do not know by the driver
although the sync signal runs via the 3-Pin Mini-Din.</span></font></div>

This is easy to fix:<br>
put a line in /etc/init.d/boot.local:<br>
mount /proc/bus/usb<br>

Dear PyMolers,<br>
<br>
We are on the process of buying a 3D monitor for stereo
rendering. The main software we use for visualization is PyMOL,
in Linux (preferably OpenSuse), so it is mandatory that it works
well with Pymol. We might use stereo with other programs like
Maestro (Schrödinger) or MOE (CCG), so if compatible with this
other software, the better.<br>
Graphics Card is a nVidiaGEFORCE QUADRO FX 1800.<br>
<br>
PyMOL official recommendations was the Zalman ZMM220W, <b>but
this is not longer distributed, at least in Europe</b>. So,
before going for any of the solutions like Samgsung or
Viewsonic, and getting deep into the nightmare of finding out
the proper X configuration, I would like to receive as much
input as possible from recent experiences of PyMOL community. <br>
<br>
Thanks in advance,<br>
<br>
Hugo<br>

<div>Just to let you all know that we have successfully tested
a Viewsonic VX2268wm (I'm guessing that is the version of
the VX2265wm sold on this side of the pond) with an nVidia
Quadro 3800 (3pin stereo version) under Fedora Core 12, with
the nVidia 3D vision glasses, and the 195beta version of the
driver.</div>
<div><br>
</div>
<div>Very high quality QB stereo under PyMOL and Coot.</div>
<div><br>
</div>
<div>By the way, Warren had warned us that the ATI drivers for
Linux were not up to scratch (without even considering
stereo). Is that still true?</div>
