Re: [chimera-dev] stereo: Linux, nvidia Quadro FX 5600
Hello, I recently experienced this same problem with a similar card. I haven't seen the exact fix posted anywhere but this thread pointed me in the right direction so I figured I'd post what I needed to do to fix this... With glxgears I'd get: glxgears -stereo Error: couldn't get an RGB, Double-buffered, Stereo visual With http://astronomy.swin.edu.au/~pbourke/opengl/stereogl/pulsar.c: ./pulsar -s ERROR: Internal error <Visual with necessary capabilities not found> in function fgOpenWindow
From the /usr/share/doc/NVIDIA_GLX-1.0/README.txt:
o Workstation overlays, stereo visuals, and the unified back buffer (UBB) are incompatible with Composite. These features will be automatically disabled when Composite is detected. Simply running: "nvidia-xconfig --no-composite" fixed it. Looks like it added the following to xorg.conf: Section "Extensions" Option "Composite" "Disable" EndSection Hopefully this helps anyone else with this problem... Thanks, Dave. *************************** On Fri, 17 Apr 2009, Randy Heiland wrote: Hello again gang, I'm guessing someone there can help me get past this - I know Greg has offered advice elsewhere.

Dave, thanks for the post! I'll be curious to see if it fixes it for us. Right now another fellow is using it booted in Vista... -Randy On Jun 4, 2009, at 8:15 PM, Dave Rager wrote:
