Just FYI, I wanted to forward this useful information from Gene Carter
regarding his successes in getting stereo hardware to work under Linux,
I thought others might benefit from this information as well.

Enjoy,

John,

I'm not on the mail list. Feel free to forward these emails.

It was neccessary to recompile vmd.

If there's something I'm missing from the list below,
let me know.

My setup...
    OS: RedHat 7.1
    Xserver: XiG's Summit Platinum, multi-head version 2.1-8
    Video Card: Matrox G450(I think 32 Mb RAM)
    CPU: Intel(R) Pentium(R) 4 CPU 1300MHz
    RAM: 256Mb
    Monitor: ViewSonic PS790
    Stereo Equipment: Stereographics Stereoeyes wired.
    VMD: 1.7.1, recompiled.
    
Notes:
    XiG offers a demo version of the server which is
    active for 20 minutes each invocation. This gives
    you ability to experiment before deciding to buy.

    After Summit is installed, and you've started the
    new Xserver, you need to use "Xsetup" to chose
    "Stereo Mode" under the OpenGL window. I chose
    WhiteLine. Restart your X server. The glasses should
    start to shutter at this point and the program "glxinfo"
    should indicate if you have stereo capability.

    If you get core dumps when you launch OpenGL programs,
    look at:
        Is your glibc at or above version 2?
        Try removing
         /usr/X11R6/lib/X11/AcceleratedX/modules/olg_sse2.mod

    It was neccessary for me to recompile VMD.

    In VMD, select "Crystal Eyes" from the stereo selections.
