我知道这在名义上是一个重复的问题，但我已经阅读了其他问题，经过几个小时的尝试后仍无法解决我的问题，所以请不要删除它。此外，其他问题的答案似乎取决于某些情况。我的情况与我发现的其他人的情况不同，这是我的问题。
最近，我安装了 Ubuntu 12.04 和 Wubi，运行正常，尽管速度很慢，偶尔会挂起。因此，我对驱动器进行了分区，并在其自己的分区中安装了 12.04。
现在当我启动它时，我只能使用 2D。我相信这是 NVIDIA 的一个错误。
我的 NVIDIA 卡是 GT 520M，我的机器有 Optimus。
附加驱动程序仅显示我的无线驱动程序。
转到系统设置 >> 详细信息 >> 图形显示驱动程序：未知，体验：标准。
我从 NVIDIA 网站下载了驱动程序，并运行安装程序，没有任何错误，只是“发行版提供的预安装脚本失败”。
重新启动后，我的屏幕卡在 640X480，通过编辑 /etc/X11/xorg.conf 解决了这个问题
然而，我仍然停留在 2D 状态，其他方面也没有任何改变。
一个帖子建议使用 Bumblebee。我试了一下，但运行时optirun firefox屏幕一片空白，卡住了。
在听取了另一个建议后，我检查了 BIOS 并尝试禁用 Optimus。
我找到并运行了无数其他命令，试图修复该问题但没有任何变化。
我刚刚重新安装了 Ubuntu. 从那里，我：
- 安装了所有更新
- 下载了 NVIDIA 驱动程序
- 已安装
- 屏幕卡在 640X480，已在 xorg.conf 中修复。
回顾：
- 我无法让 NVIDIA 驱动程序正常工作
- 我无法使用 2D
- 我是个白痴
我认为如果第一个问题解决了，第二个问题自然就会解决。如果您需要我提供任何其他信息，我很乐意提供。
从我在其他帖子中看到的内容来看，我认为这些信息可能会有所帮助：

更新：
根据评论，安装了 Bumblebee。现在正在重启，看看是否有帮助。
重启完毕 - 没有变化。
更新：
@Constantin：BIOS 列出了两个选项：“可切换”和“集成”。我试过了，不行。我试了你链接的说明 - 没有变化。nvidia-xconfig 和 nvidia-settings：完成、完成、重做。没有变化。
另外值得注意的是，我已经恢复了按照该链接中的说明所做的所有更改。
答案1
OP 发帖：
找到解决方案了！昨晚多次重启后，似乎偶然出现了 Unity 3D，附加驱动程序现在列出了两个 NVIDIA 驱动程序。然后我愚蠢地尝试安装这些驱动程序 - 搞坏了它。
然而，这给了我希望，我找到了解决方案。我没有让 NVIDIA 驱动程序工作，但我认为我的 Nouveau 驱动程序可以工作。无论如何，Unity 3D 运行良好。
我采取的步骤：
- 再次进行全新安装。
- 已安装所有更新。
- 打开终端，运行 apt-get purge nvidia-settings nvidia-current。
- 重启
- 这让我得到了 Unity 3D，并且我推断，图形驱动程序可以正常工作。也来得正是时候。
答案2
Linux 上的 NVIDIA Optimus 没有官方解决方案。为了使其正常工作，请尝试安装 Bumblebee： https://wiki.ubuntu.com/Bumblebee
答案3
一些可能有助于解决您的问题的想法：
- 尝试从 BIOS 禁用 Optimus（联想允许您这样做）
- http://ubuntuforums.org/showthread.php?t=1467074- 按照这里的一些步骤操作，显然您没有从 PPA 安装驱动程序，因此您不必清除。
nvidia-xconfig从控制台运行 sudonvidia-settings从控制台运行- 如果一切都失败了，请卸载您使用的驱动程序...我认为，您必须谷歌一下，它是
sudo sh NVIDIA_[DRIVER BINARY FILE].sh --uninstall类似这样的内容，然后安装 PPA，只需谷歌“12.04 nvidia 驱动程序”
