尝试使用带有英特尔集成显卡和独立显卡的 3 台显示器

Question

我目前在台式机上运行 Ubuntu 12.04 LTS，台式机有英特尔 i7 2600k，集成英特尔 HD 3000 显卡和 GeForce GT430 1GB 显卡。我有 2 台显示器（垂直方向）通过 DVI 连接到 GT430 卡，一台显示器（水平方向）连接到主板上的 DVI 端口。我可以毫无问题地运行两个垂直显示器，但我无法让第三个显示器工作，过去不断显示 Ubuntu 加载屏幕。我已经在 BIOS 中将英特尔集成显卡设置为“始终启用”，并且一直在使用 xorg.conf 文件，但似乎无法使其正常工作。

这是我的 xorg.conf 文件的当前副本：

有谁知道根据我的设置，我想要做的事情是否可行？如果是这样，我怎样才能让它工作？
