I didn't know that nvidia had workstation and consumer version of their drivers. In any case the only 91.36 version that I found was at http://www.nvidia.com/object/winxp_2k_91.36 If I install this driver I don't see any stereo setting when I get to the video driver setting menu. Chimera stereo doesn't work either. In the NVIDIA web site there is a consumer stereo driver at: http://www.nvidia.com/object/3dstereo_91.31 The web site says that it requires 91.31 ForceWare Graphics drivers to run. I have tried the following permutations so far and I always get an error message when trying to go in stereo mode with chimera. 1 - NVIDIA driver for Quadro4 downloaded from DELL support web site. (driver version?. date 2004)). This one seems to have native stereo support (at least it has a menu saying so). 2 - NVIDIA ForceWare driver 91.36 & Consumer stereo driver 91.31. 3 - NVIDIA ForceWare driver 91.31 & Consumer stereo driver 91.31. With options 2 and 3 there are is a test option in the driver menu. This test seem to run OK (i.e. I can see the two stereo images in a scene alternating rapidly). Yet chimera gives an error message when I tried the stereo mode (or calling the program with chimera --stereo). Maybe none of the above are the correct drivers ?. Maybe I need to reinstall chimera after installing the drivers ?. Thanks Hernando Greg Couch wrote:

How can I use stereo (sequential mode) ?. If I click the stereo button in the camera dialog or start chimera using the command chimera --stereo. I get the error message:

My graphic cards is a NVIDIA Quadro4 900 XGL. The Nvdia Stereo driver (v: 91.31) is installed and enabled. Chimera version is: 1 build 2255 2006/06/23

I've made your mistake, you need to remove the NVidia Consumer Stereo driver -- the Quadro driver supports stereo natively. The Consumer Stereo driver is for GeForce graphics cards (ie., consumer graphics cards, not workstation graphics cards).
The lastest Quadro driver is version 91.36.
You still need to configure the Quadro graphics driver for stereo after you install it.
