我自己修复了这个问题。由于我也安装了最新的驱动程序,所以我偶然发现了这个帖子;安装最新的英特尔驱动程序后,Nvidia(Bumblebee)无法加载
但我按照说明做了:
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,所以我又搜索了一下。我找到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,成功了!
