我安装了 Xubuntu 11.04。它检测到了我的 Nvidia 显卡，我有驱动程序，但它说驱动程序未被使用，我应该运行 nvidia-xconfig
因此我以 root 身份运行了 nvidia-xconfig，它备份了我的 xorg.conf，但当我重新启动时，X 无法启动。我得到的是命令，而不是 X 屏幕。我必须登录命令行并恢复我的 xorg.conf。我还尝试添加 BusID“PCI:1.0.0”，但没有帮助，X 无法启动。
这是我的 xorg.conf，它不能与 Nvidia 一起使用：
Section "Monitor"
Identifier "Monitor0"
VendorName "Unknown"
ModelName "Unknown"
HorizSync 28.0 - 33.0
VertRefresh 43.0 - 72.0
Option "DPMS"
EndSection
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BusID "PCI:1.0.0"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"

EndSubSection
EndSection

如果您的配置启用了 Nvidia Optimus，那么您必须添加处理 Linux 版 Optimus 的 bumblebee 项目的 PPA。
实际上，在 Dell XPS 15 中，您有一个板载图形芯片组 INTEL HD 3000 和一个独立显卡 NVIDIA GT525M 或 GT540M（甚至 GT550 或 555M）。Optimus 在两张卡之间切换以节省电量并延长电池寿命。
Google：Bumblebee 项目（Linux Nvidia Optimus）前往他们的启动板网站并将 PPA 添加到您的软件源中......
无论如何，请按照网站上的说明进行操作。最后，您将能够正确使用 Nvidia 卡。无需下载和安装 Nvidia 旧版驱动程序！Bumblebee 会处理好一切。
Bumblebee 是免费且开源的。
