我目前在一台台式机上运行 Ubuntu 12.04 LTS，该台式机配有 Intel i7 2600k、集成 Intel 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，还有一台显示器（水平方向），连接到主板上的 DVI 端口。我可以毫无问题地运行这两台垂直显示器，但我无法让第三台显示器工作，只能不断显示 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”，并且一直在摆弄 xorg.conf 文件，但似乎无法让它正常工作。
这是我的 xorg.conf 文件的当前副本：

有人知道根据我的设置是否可以实现我所尝试的操作吗？如果可以，我该如何实现它？
如能得到任何帮助，我们将不胜感激，并提前谢谢您。
