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:
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.

Hello again gang,
I'm guessing someone there can help me get past this - I know Greg has offered advice elsewhere.
My subject line says it all - I want to get stereo working on this machine. Trying something more basic than chimera:
$ glxgears -stereo Error: couldn't get an RGB, Double-buffered, Stereo visual
$ glxinfo -v|grep stereo bufferSize=32 level=0 renderType=rgba doubleBuffer=1 stereo=0 bufferSize=32 level=0 renderType=rgba doubleBuffer=1 stereo=0 ...
It's not obvious to me where/how one enables stereo via System-
Prefs- More Prefs->nvidia x server settings
The specs: Linux-x86_64 nvidia driver version: 180.29
GPU 0 (Quadro FX 5600) mem 1536 MB PCI Express 16x X screens: Screen 0 Display: Apple Cinema HDDisplay (DFP-1)
GPU 1 (Quadro NVS 290) 256 MB PCI Express 16x X screens: none Display: none
with an Apple 30" Cinema HDDisplay currently attached (and a ViewSonic Fuhzion, 120Hz as something else to experiment with). Currently have CrystalEyes.
I'd welcome any advice you might have. thanks, Randy _______________________________________________ Chimera-dev mailing list Chimera-dev@cgl.ucsf.edu http://www.cgl.ucsf.edu/mailman/listinfo/chimera-dev
