I have two Nvidia cards and 3 monitors. My current config file is this...# nvidia-settings: X configuration file generated by nvidia-settings# nvidia-settings:  version 319.72  (pbuilder@cake)  Sat Nov 23 16:37:04 UTC 2013Section ServerLayout    Identifier     Layout0    Screen      0  Screen0 0 75    Screen      1  Screen1 3280 75    Screen      2  Screen2 1600 0    InputDevice    Keyboard0 CoreKeyboard    InputDevice    Mouse0 CorePointer    Option         Xinerama 1EndSectionSection FilesEndSectionSection InputDevice    # generated from default    Identifier     Mouse0    Driver         mouse    Option         Protocol auto    Option         Device /dev/psaux    Option         Emulate3Buttons no    Option         ZAxisMapping 4 5EndSectionSection InputDevice    # generated from default    Identifier     Keyboard0    Driver         kbdEndSectionSection Monitor    # HorizSync source: edid, VertRefresh source: edid    Identifier     Monitor0    VendorName     Unknown    ModelName      HannStar Display Corp HZ201H    HorizSync       30.0 - 85.0    VertRefresh     50.0 - 75.0    Option         DPMSEndSectionSection Monitor    # HorizSync source: edid, VertRefresh source: edid    Identifier     Monitor1    VendorName     Unknown    ModelName      HannStar Display Corp HZ201H    HorizSync       30.0 - 85.0    VertRefresh     50.0 - 75.0    Option         DPMSEndSectionSection Monitor    # HorizSync source: edid, VertRefresh source: edid    Identifier     Monitor2    VendorName     Unknown    ModelName      Acer AL2216W    HorizSync       31.0 - 84.0    VertRefresh     56.0 - 77.0    Option         DPMSEndSectionSection Device    Identifier     Device0    Driver         nvidia    VendorName     NVIDIA Corporation    BoardName      GeForce GT 610    BusID          PCI:3:0:0EndSectionSection Device    Identifier     Device1    Driver         nvidia    VendorName     NVIDIA Corporation    BoardName      GeForce GT 520    BusID          PCI:1:0:0    Screen          0EndSectionSection Device    Identifier     Device2    Driver         nvidia    VendorName     NVIDIA Corporation    BoardName      GeForce GT 520    BusID          PCI:1:0:0    Screen          1EndSectionSection Screen    Identifier     Screen0    Device         Device0    Monitor        Monitor0    DefaultDepth    24    Option         Stereo 0    Option         metamodes nvidia-auto-select +0+0    SubSection     Display        Depth       24    EndSubSectionEndSectionSection Screen    Identifier     Screen1    Device         Device1    Monitor        Monitor1    DefaultDepth    24    Option         Stereo 0    Option         metamodes DFP-0: nvidia-auto-select +0+0    SubSection     Display        Depth       24    EndSubSectionEndSectionSection Screen    Identifier     Screen2    Device         Device2    Monitor        Monitor2    DefaultDepth    24    Option         Stereo 0    Option         metamodes DFP-1: nvidia-auto-select +0+0    SubSection     Display        Depth       24    EndSubSectionEndSectionSection Extensions    Option         Composite DisableEndSectionAll the screens work, but, Gnome is running in Fallback mode.
Is it possible to have multiple screens using multiple video cards with Gnome3 standard experience?
