1：安装epel源：

sudo rpm -ivh epel-release-7.5.noarch.rpm  

2：安装elrepo源：

 sudo rpm -Uvh elrepo-release-7.0-4.1.x86_64.rpm

3：依赖安装bumblebee

sudo yum install bumblebee

4:修改/etc/bumblebee/bumblebee.conf中的driver-nvidia]中的ernelDrive为nvidia

# Module name to load, defaults to Driver if empty or unset
<span style="color:#FF0000;"><strong>KernelDriver=nvidia</strong></span>
PMMethod=auto

5：重启。

6：查看NVIDIA显卡是否是rev ff状态。

7：测试女idia显卡驱动正常安装：

optirun  glxspheres64

备注：

在多次使用optirun之后可能会出现

可以修改etc/bumblebee/bumblebee.conf：

Driver=nvidia
KernelDriver=nvidia-current
