quadobuffered stereo with quadro go 700? laptop quad-buffered stereo
I am trying to set up quad-buffered stereo on a Dell Precision M60 (running Fedora Core 6)
for use in developing stereoscopic software to run on another machine at a university lab.
This machine has a Quadro FX go 700 mini-pci graphics card.
I have set up two Fedora desktop machines with quadro cards, so I may know the right options for the xorg.conf file. But the stereo programs die, complaining of missing capasities:
[quote]freeglut (./bumps): ERROR: Internal error <Visual with necessary capabilities not found> in function fgOpenWindow [....]
[/quote]
So, the first question: does the Quadro FX go 700 card [ NV31GL ] support or not support
quad-buffered stereo?
I'm including the xorg.config where I added the appropriate options; the nvidia-xconfig tool for some reason moved the card options to the "screen" section, which didn't seem right
to me (and still didn't allow stereo to work).
--- I guess I CAN'T upload my xorg.conf file. I keep getting a "Upload failed. You are not permitted to upload a file with that file extension." even if I rename the file so that there's NO extension. (*sigh*)

Are you kernel, driver & X stable, not beta?
And read the log-file. After the line ' option "stereo" ' may be some explanations.

I got this working, and forgot to update this entry [whoops! -sorry].
I no longer remember what I needed to do to get it working, but
I suspect that it was another kernel version/driver version problem,
or config file problem. (I remember some effort at rebuilding the
xorg.conf file from scratch).
This effort was followed by a heavy effort to get the linux wireless working
(without success), which seems to have overwritten my memory of the earlier effort.
There are some things worth noting. One of my contacts (Carlos C.)
has found that older machines using the unified nVidia drivers,
because they use software emulation for some capacities,
can have huge performance hits when an OpenGL program triggers
the emulation mode. Evidently, using a texture with a non-power-of-2
dimension is one of those triggers. (On one machine this was about 3000x performance difference).
I think using mipmaps implicitly solves this problem, even if you don't need the
additional scaled textures. There are other ways of making your original texture
power-of-2-dimensioned; Carlos recommends padding the texture to power-of-2,
and then using the appropriate subregion.
