Bumblebee 无法找到库路径这一事实对我来说很奇怪，因为我最近才更新了 bumblebee.conf，如下所示：

## Section with nvidia driver specific options, only parsed if Driver=nvidia
[driver-nvidia]
# Module name to load, defaults to Driver if empty or unset
KernelDriver=nvidia-331
PMMethod=auto
# colon-separated path to the nvidia libraries
LibraryPath=/usr/lib/nvidia-331:/usr/lib32/nvidia-331
# comma-separated path of the directory containing nvidia_drv.so and the
# default Xorg modules path
XorgModulePath=/usr/lib/nvidia-331/xorg,/usr/lib/xorg/modules
XorgConfFile=/etc/bumblebee/xorg.conf.nvidia

我的笔记本电脑使用的是 Gefore GT 525M。所有模块似乎都已安装到位：

~$ find /lib/modules/$(uname -r) -name 'nvidia*.ko*'
/lib/modules/3.13.0-24-generic/updates/dkms/nvidia_331.ko
/lib/modules/3.13.0-24-generic/kernel/drivers/video/nvidia/nvidiafb.ko
~$ find /usr/ -name 'nvidia_drv.so'
/usr/lib/nvidia-331/xorg/nvidia_drv.so
find: `/usr/share/doc/google-chrome-stable': Permission denied

我刚刚更新了 Bumblebee。为什么我无法使用 Bumblebee 在我的显卡上运行程序？

答案1

删除 bumblebee 和 libvdpau-va-gl1

sudo apt-get purge bumblebee*  
sudo apt-get purge libvdpau-va-gl1

安装 nvidia-prime 和 nVida 驱动器和 nvidia-settings 319

sudo apt-get install nvidia-319 nvidia-settings-319 nvidia-prime

并安装主要指示器

sudo add-apt-repository ppa:nilarimogard/webupd8 
sudo apt-get update
sudo apt-get install prime-indicator

重启。
