Hi,
 
For supporting a wide variety of software I think it would be the best choice to have an openGL quad buffered stereo device running.
The fact that Harry did have success with a 120 Hz TFT-Monitor, the Quadro FX3800 (3-Pin Mini-Din) with 195.x drivers and 3D-Vision Glasses under Linux is due to the fact that he uses a Linux distribution which is related to RHEL.
 
I just tried exactly 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.

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

I have 4 systems up runnig openSuse 11.2
Another question of concern is wether the chipset on the FX1800 is supported by the 195.x driver at all. You should look this up with nvidia.
 
Regards,
 
Joachim

Betreff: Re: [PyMOL] Viewsonic VX2268wm confirmed to work in stereo under Linux

Dear PyMolers,

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.
Graphics Card is a nVidiaGEFORCE QUADRO FX 1800.

PyMOL official recommendations was the Zalman ZMM220W, but this is not longer distributed, at least in Europe. 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.

Thanks in advance,

Hugo

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.

Very high quality QB stereo under PyMOL and Coot.

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?

Thanks

Harry
