Sometimes it 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
 +

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.
