    笔记本型号：Lenovo ideaPad Y470
    安装完15正式版后，首先在驱动管理器里将闭源显卡驱动装上（版本号：352）

    发现装上该闭源驱动后，实际上还安装了bumblebee，尝试在终端中键入optirun -vvv google-chrome，有如下报错：
    1. steve@steve-deepin-y470:~$ optirun -vvv google-chrome

    Copy the Code
    另外不知道如何打开nvidia-prime，望大虾指教！

    LibraryPath=/usr/lib/nvidia-319-updates:/usr/lib32/nvidia-319-updates
    XorgModulePath=/usr/lib/nvidia-319-updates/xorg,/usr/lib/xorg/modules
