双显示器不适用于 Nvidia 卡

Question

甚至我的主显示器也显示为未知。我曾尝试使用 Nvidia 设置设置双显示器，但没有任何乐趣，但它确实识别出我有 2 个显示器。

这在 11.04 中不是问题。我对 Nvidia 设置的问题似乎是我的 2 台显示器需要不同的分辨率，但即使我将它们设置为它们都可以处理的分辨率，它也只会出现在克隆模式下。我真的希望有人可以提供帮助，否则我将不得不回滚到 11.04。

为什么 Ubuntu 11.10 不能识别我有 2 个显示器？

这是我的内容xorg.conf：

好的，我试过 disper -e。问题是 Nvidia 设置似乎将两台显示器视为同一台显示器。因此，将设置更改为一个没有任何效果，但更改另一个设置，它会对两个屏幕产生相同的影响。

结果disper -l如下：

几分钟前我在我的系统上解决了这个问题。对我来说，它的工作方式如下：

1. 安装了发布后的 nvidia 驱动程序。
2. 开始nvidia-settings配置我的双屏，你必须使用 TwinView（不是单独的 X-Config），不要忘记选择一个主显示器。我在配置过程中遇到的问题是，如果我选择左显示器作为主显示器，它似乎只能工作。要测试，您可以使用应用按钮。 如果一切正常，您可以保存到 X 配置文件。

如果你想阅读它，这里是我生成的 xorg.conf：
