problem of configuring stereo in xorg.conf

[Donglu Xie]

Hi Andrew,

Thank you very much. Under the help of one of PyMol users, at last figure
out the right configuration. It needs "AllowDFPStereo" on in LCD and
""XineramaStereoFlipping" on in CRT. Following is the part I changed:

====== begin the partial xorg.conf ========

# for CRT
Section "Device"
        Identifier  "Videocard0"
        Driver      "nvidia"
        VendorName  "Videocard vendor"
        BoardName   "NVIDIA Quadro FX3400"
        BusID       "PCI:5:0:0"
        Option      "Stereo" "3"
        Screen     0
        Option     "UBB"   "1"
        Option     "NoPowerConnectorCheck"
        Option       "XineramaStereoFlipping" "1"
EndSection


# for LCD
Section "Device"
        Identifier  "Videocard1"
        Driver      "nvidia"
        VendorName  "Videocard vendor"
        BoardName   "NVIDIA Quadro FX3400"
        BusID       "PCI:5:0:0"
        Screen      1
        Option     "UBB"   "1"
        Option     "Stereo"   "3"
        Option     "NoPowerConnectorCheck"
        Option       "AllowDFPStereo" "1"
EndSection

========== end ========

Bests,
