让两张显卡在两个屏幕上工作

我有 2 张 nVidia GeForce GTS 450/PCIe/SSE2 显卡，每张都有 DVI、VGA 和 HDMI 端口。

不幸的是，Ubuntu 只能检测到其中一张卡，所以我必须将一个屏幕设置为 VGA，将另一个设置为 DVI。我希望两个屏幕都设置为 DVI。

我正在使用 Ubuntu 14.04 GNOME，已完全更新。它从未与 12.04 unity 或 14.04 unity 兼容。

我很乐意编辑任何信息（但我不知道现在需要什么）。

我终于让它工作了，2张显卡（nVidia GTS 450）两个屏幕都在DVI上。

这是我的xorg.conf：

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0" 0 0
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
    Option         "Xinerama" "0"
EndSection

    BusID          "PCI:1:0:0"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "Stereo" "0"
    Option         "nvidiaXineramaInfoOrder" "CRT-0"
    Option         "metamodes" "GPU-56281125-01c7-ee85-b8b9-b3e5cf94b7c5.GPU-0.DVI-I-0: nvidia-auto-select +0+180, GPU-cbc59e3f-e8c1-a347-a069-b62f6b885f7d.GPU-1.DVI-I-0: nvidia-auto-select +3600+0 {rotation=right}, GPU-cbc59e3f-e8c1-a347-a069-b62f6b885f7d.GPU-1.DVI-I-3: nvidia-auto-select +1680+180"
    Option         "MultiGPU" "Off"
    Option         "SLI" "off"
    Option         "BaseMosaic" "on"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

请注意，它仅引用 1 个 GPU，因此不需要另一个 X Screen。
