双显示器设置不再有效！

使用 Nvidia GeForce 9500 卡运行 Fedora 14

几天前，我更换了一台 20 英寸 LCD（我有两个相同的 20 英寸 LCD）。我能够将 20 英寸换成新的 24 英寸 LCD，当然，由于分辨率的原因，显示会失真。因此，我备份了我的 xorg.conf 文件，并决定运行 nvidia-setting 来配置分辨率。我重新启动，结果只有一个显示器可以工作，即 24 英寸的显示器。另一个显示器拒绝启动，我不知道为什么。我想知道是不是一个 DVI 端口坏了​​。我交换了两根 DVI 电缆，输出到我的 20 英寸显示器可以工作，但我的 24 英寸显示器变黑了。唯一的变化是简单地更换了显示器。

这是我的 xorg.conf 文件：
