You can do passive stereo with a dual-output card.
Cards that we have been able to do this with under Linux are the
Evans & Sutherland Tornado 3000 (using Xi Graphics' LGD driver),
Matrox G450 (with Xi Graphics driver; XFree86's DRI may also work),
nVidia GeForce2MX cards such as the ASUS V7100 & Inno3D Tornado,
and the nVidia Quadro2MXR-based Elsa Synergy III.
The Wildcat 5110 may be another option in the future; 3DLabs say they are
working on Linux drivers, but haven't released anything yet.
In theory you could also use multiple PCI nVidia cards to get 2 (or more)
video channels. However, when I tried this recently, Performer apps gave
the error:
PF Warning(2): Linux: pfMultipipe(2) ignored - Not supported
A question for the SGI folks then: will this be corrected in the future?
(I was using the evaluation version of 2.4, if that makes a difference.)
Regarding active, quad-buffered stereo, so far we have not found any cards
that support it under Linux. Xi Graphics claims that their next (2.0)
LGD X server will support stereo, which may mean quad-buffered stereo, but
we haven't seen that yet.
