无法访问辅助GPU – 错误：无法加载GPU驱动程序
我尝试了多个不同的驱动器，nvidia-340，nvidia-331，nvidia-331-updates，nvidia-343，结果相同：

我自己修好了。 我偶然发现了这个post，因为我也安装了最新的驱动程序; 安装最新的英特尔驱动程序后，Nvidia（大黄蜂）无法加载
但我做了指示：
sudo apt-get purge i915-3.15-3.13-dkms sudo apt-get install --reinstall xserver-xorg-video-intel libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core sudo dpkg-reconfigure xserver-xorg sudo apt-get install --reinstall nvidia-340 sudo dpkg-reconfigure bbswitch-dkms sudo reboot
但它对我不起作用，所以我搜索了一些。 我发现了这个错误报告并尝试了这些说明（ https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1310023 ）：
sudo ldconfig -n sudo update-initramfs -u sudo reboot
尤里卡，它奏效了！
