Sometimes it is handy to configure two Desktops: one on a CRT monitor that can do stereo-graphics, and one on an LCD monitor for the more regular work, eg your refinement jobs with CCP4. For Nvidia cards you need to modify the xorg.conf file to have a section more or less like that:
<code>
Section "Monitor"
    Identifier    "Monitor0"
    VendorName    "Iiyama"
    ModelName      "Vision Master Pro 512"
    DisplaySize    450      330
    HorizSync      31.5 - 120.0
    VertRefresh    50.0 - 150.0
    Option        "dpms"
EndSection
Section "Monitor"
    Identifier    "Monitor1"
    VendorName    "Philips"
    ModelName      "150B"
EndSection
Section "Device"
    Identifier    "Videocard0"
    Driver        "nvidia"
    VendorName    "Videocard vendor"
    BoardName      "NVIDIA Quadro FX (generic)"
    BusId          "PCI:1:0:0"
    Screen        0
EndSection
Section "Device"
    Identifier    "Videocard1"
    Driver        "nvidia"
    VendorName    "Videocard vendor"
    BoardName      "NVIDIA Quadro FX (generic)"
    Option        "Stereo" "3"
    BusId          "PCI:1:0:0"
    Screen        1
EndSection
Section "Screen"
    Identifier    "Screen0"
    Device        "Videocard0"
    Monitor        "Monitor0"
    DefaultDepth    24
    SubSection    "Display"
        Viewport    0 0
        Depth      24
        Modes      "1024x768" "800x600"
    EndSubSection
EndSection
Section "Screen"
    Identifier    "Screen1"
    Device        "Videocard1"
    Monitor        "Monitor1"
    DefaultDepth    24
    SubSection    "Display"
        Viewport    0 0
        Depth      24
        Modes      "1600x1280" "1280x1024" "1024x768" "800x600"
</code>
Note that one can think this is rather silly to define two card, two monitors, two cards, and two screens.
However, that the only way I know that one monitor can be streo-enabled and the other one not.
