我有一台华硕 UL50Vt，配有 nvidia optimus 混合显卡 (GeForce 210M)。我最近安装了 ubuntu 12.04，在“详细信息”应用程序中，它显示我使用的是英特尔视频驱动程序。因此，我安装了 bumblebee，重新启动后，“详细信息”显示“VESA：GT218 主板 - 0698a740”由于 VESA 与 NVIDIA 不同，我卸载了 bumblebee，但错误并没有消失 :(
现在我的 Xorg.0.log 包含：
cat /var/log/Xorg.0.log | grep nvidia
[ 12.616] (II) LoadModule: "nvidia"
[ 12.634] (WW) Warning, couldn't open module nvidia

附加驱动程序表明 NVIDIA 已激活但目前未使用：
jockey-text --list | grep nvidia
kmod:nvidia_current - nvidia_current (Proprietary, Disabled, Not in use)
kmod:nvidia_current_updates - nvidia_current_updates (Proprietary, Enabled, Not in use)
kmod:nvidia_experimental_304 - Experimental NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use)
kmod:nvidia_experimental_310 - Experimental NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use)
NVIDIA X Server Settings 在启动时写入：
您似乎没有使用 NVIDIA X 驱动程序。请编辑您的 X 配置文件（只需nvidia-xconfig以 root 身份运行），然后重新启动 X 服务器。
建议来自https://askubuntu.com/a/121612/165811
sudo apt-get install linux-headers-`uname -r`
sudo dpkg-reconfigure nvidia-current
sudo nvidia-xconfig
sudo reboot
没有任何变化。我仍然使用后备 VESA 驱动程序。分辨率为 1280x768，而不是 1366x768。
我如何才能找出为什么 nvidia-current 无法加载 nvidia 模块（我相信该模块存在）：
modprobe -l | grep nvidia
kernel/drivers/video/nvidia/nvidiafb.ko
kernel/drivers/net/ethernet/nvidia/forcedeth.ko
updates/dkms/nvidia_current.ko
updates/dkms/nvidia_current_updates.ko
updates/dkms/nvidia.ko
如果有帮助的话，这是我的 xorg.conf：
cat /etc/X11/xorg.conf
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 304.88 (buildmeister@swio-display-x86-rhel47-06) Wed Mar 27 15:32:58 PDT 2013

另外，如何切换到之前为我提供良好服务的板载英特尔显卡？

答案1
我建议您卸载 nvidia 驱动程序并确保您正在运行 intel 驱动程序。此后，请按照 wiki 中的说明进行操作： https://wiki.ubuntu.com/Bumblebee
请报告在按照指南中指定的方式运行时可能遇到的任何具体问题。
祝你好运！
