Ok so this really requires more information. Our stereo is set up for
shutter glasses. This means you need to have a display device that can
refresh quickly enough. (~120Hz) It sounds like you have this... This
gives us left and right eye at 60Hz each... I know we have made this
work at a lower refresh rate for a larger display. If I remember
correctly Option "Stereo" "3" is correct for shutter glasses.
When I first got this working on linux, I had to have a Quadro card to
get stereo enabled in the driver, I'm not sure if this is still true.
We attempt to get a context that supports stereo when you start up, if
you can get such a context the stereo button will not be greyed out.
I haven't done this myself for a number of years, but if you need
additional help I am happy to do so.
