不久前我安装了 elementary OS Freya。我花了几天时间才为我非典型的多显示器设置找到正确的配置
2 块 NVIDIA 显卡 GeForce GTX 660 Ti 和 GeForce 9800 GT
01:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 660 Ti] (rev a1)
02:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce 9800 GT] (rev a2)
5 个显示器：左侧为 DELL 2407WFP（纵向）、HP LP2465（纵向），中间为 Samsung SyncMaster 305T（横向）、HP LP2465（纵向）、右侧为 HP LP2465（纵向）。左侧和中间的 2 个显示器中，1 个连接到 GeForce GTX 660 Ti，右侧的 2 个显示器连接到 GeForce 9800 GT。

在 nvidia autoconf 上，只有左侧和中间的显示器可以正常显示，但右侧的两个显示器是暗的... 我可以在它们上面移动光标，但除此之外什么也做不了。我意识到这样我什么也得不到。
现在我正在为这个设置编写 xorg.conf。我正在寻找类似的配置，并遇到了这个。我用了一点来做我自己的，但我不确定是否可以。如果您能帮我完成此配置，我将不胜感激。

答案1
Nvidia 有一个应用说明，描述了如何使用 (2) Quadro 卡和 4 个显示器。我有一个工作设置，其中只有一个 Quadro 卡和 4 个显示器，仅使用 MetaModes 选项。
Option "MetaModes" "1920x1080 +0+0, 1920x1080 +1920+0, 1920x1080 +0+1080, 1920x1080 +1920+1080"
