Dear all, Been watching this thread for a few days now. Cant resist the urge to point out there are stereo solutions on the market that do not need shutter glasses, don't need graphics cards with stereo DIN plugs and work with any dual head graphics card that supports OpenGL. This info is, of course, of absolutely no use to those of you stuck with shutter-glass systems, but something to keep in mind for your next HW upgrade! Also, keep in mind the day will come (some of us believe in the near-future) when CRTs are no longer available - what will you use then? I'm biased of course and would say look first at our technology as the only commercially available zero cross-talk, UXGA resolution, glasses-free solution on the market. The IRIS platform's elegance is its simplicity - comparable to dual head passive projection systems, but without glasses. Sure, it's a premium-priced product, but ask yourself how much do you value your time/sanity and then consider how much you would pay for an easy life without any more calls to so called tech-support teams. On a practical level, how many sets of shutter glasses do you break in 1-year (at several hundred $$$ a set) and how many graphics cards are consigned to the bin when you discover you need a stereo-DIN connector for your fancy new stereo workstation? Best of luck to you all in your quest for better stereo!

Unfortunately, nothing I tried resolve the problem yet. I guess Carsten's concern about the insufficient power sounds quite convincing. For instance, The red LED of the emitter flashes when I change the display settings using ctrl+alt+keypad plus. And somehow it gets a signal from the mouse when I am in stereo mode. Moving the mouse turns on the LED for a few seconds, then it is off again. Klaas, thank you too. Option "Overlay" did not change anything, unfortunately. I guess the quickest solution is to switch to a Quadro card with 3-pin mini-DIN plug. Very interesting to read Julien's comment about dealing with REAL D / NVIDIA ... vriendelijke groeten, Thomas. for the record: I think I am using the most recent NVIDIA driver: NVIDIA-Linux-x86_64-1.0-8774-pkg2.run machine architecture: Linux 2.6.9-42.0.2.ELsmp x86_64 On Sep 11, 2006, at 5:38 PM, Schubert, Carsten [PRDUS] wrote: Sridhar, Thomas: If I am not mistaken, the power from the VGA port on some graphics chips is not sufficient to power the emitter. We had a scenario were we tried to get stereo to work from a laptop with a FX1400 card (w/o DIN plug) and a BlueLine stereo enabler and encountered the same problem (under RHEL3 and 4). The solution was to buy a self powered emitter from Stereographics. Sorry, can't give you the part number right now, somebody else borrowed the machine, but call Stereographics, they should be able to help.

Unlike the SGI's, the emitter is not on all the time, only when being called. So, my emitter is on when I run pymol (always for that program), and it is on when I run stereo in coot, but if I turn stereo off in coot, the red light goes off. I also believe it is on full time when I run O, but I don't remember right off for that one (I know it comes on when I turn stereo on). The fact that you get a red light means you probably are calling it right. Does it go off in the middle of an application? What do you mean that the red light comes on sometimes? Dave Roberts "Sridhar Prasad" <[EMAIL PROTECTED]> 09/11/06 4:06 PM >>> Thomas, I am also having very similar problem, I have been trying to run Pymol on RHEL4 with an nVIDIA Quadro NVS 285 graphics card, and the hardware stereo does not work. Since my computer also does not have a 3-pin mini-DIN plug, I have been using an emitter with StereoEnabler from Nuvision. Thanks Sridhar Dr. G. Sridhar Prasad, Ph. D.

According to REAL D the card should be able to do stereo (using an emitter with StereoEnabler, since it does not have a 3-pin mini-DIN plug). My monitor (SGI 24inch widescreen GDM-FW9011) shows the interlaced stereo image but the emitter does not properly produce a signal. The red LED of the emitter occasionally lights up, but does not stay lit. I tried various screen resolutions / refresh rate settings, none work. If anyone out there is running stereo on this card or another nVIDIA Quadro card without 3-pin mini-DIN I would be very curious to take a look at the working /etc/X11/xorg.conf file.
