Did you install the drivers using jockey or using an unsupported method?

Twinview utilizes xorg.conf, so put something like this in it:
Change your values for "Device" and "Monitor" according to your hardware. Not 
all values are needed. You can experiment with removing things like HorizSync 
and VertRefresh. Check your BusID with lspci.

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce GT 216"
    BusID          "PCI:1:0:0"
    Screen          0
EndSection

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Eizo"
    ModelName      "ColorEdge CG210"
    HorizSync       24.0 - 100.0
    VertRefresh     49.0 - 86.0
    Option         "DPMS"
EndSection

Section "Monitor"
    Identifier     "Monitor1"
    VendorName     "Eizo"
    ModelName      "ColorEdge CG210"
    HorizSync       24.0 - 100.0
    VertRefresh     49.0 - 86.0
    Option         "DPMS"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    DefaultDepth    24
    Option         "TwinView" "1"
