我正在运行 Ubuntu13.10 - 我有一台戴尔 Latitiude E6530 笔记本电脑，它有一个英特尔 CPU+GPU 和一个 NVidia NVS 5200M GPU。在英特尔高清内置显卡下，系统运行良好，我愚蠢地尝试安装 NVidia 驱动程序，这很麻烦。长话短说，我一无所获，无法让我的系统恢复使用英特尔集成显卡。我尝试了各种明显的技巧（我读了很多论坛帖子！！），但我无法让英特尔 GPU 驱动程序/硬件检测恢复。
我目前正在使用 NVidia 卡在“nouveau”下运行，速度很慢，但至少我可以看到我的屏幕来输入这些内容 :(
有人能帮我恢复原始的英特尔显卡吗？
真正奇怪的是，英特尔 GPU 似乎消失了从可用硬件列表中？

^^^ 这是我期望看到的，英特尔和 NVIDIA 卡 - 我的现在缺少英特尔卡。还要注意的是，英特尔 GPU不是列在我的 lspci 输出中！
还有他的 lspci 的前几行：

^^^ 再次重申，这正是我希望看到的！
我尝试过显而易见的 --reinstall X 组件（包括 -intel 位），但没什么区别，我尝试过将 intel 部分添加到 xorg.conf，它会加载然后卸载 intel 驱动程序。我猜是因为它认为我不再有 intel GPU 了？！
我认为这是因为 NVidia 驱动程序在内核级别进行了可怕的修改...是否可以再次检测到 Intel VGA 硬件？
答案1
解决方案是在 Dell BIOS 的视频部分下重新启用 Optimus。然后英特尔集成 GPU 被恢复到硬件列表中，Ubuntu 正确检测到它并使用默认驱动程序。
我实际上不记得改变过该设置，但在使用 NVidia 驱动程序时我一定尝试过。
