安装elrepo库

查看新版本

yum install lynx

lynx  https://mirrors.tuna.tsinghua.edu.cn/elrepo/extras/el7/x86_64/RPMS/

安装

rpm -Uvh   https://mirrors.tuna.tsinghua.edu.cn/elrepo/extras/el7/x86_64/RPMS/elrepo-release-7.0-3.el7.elrepo.noarch.rpm

查看显卡型号是否支持双显卡

lspci  | grep VGA

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07)

lspci  | grep 3D

01:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 940MX] (rev a2)

安装nvidia-detect检查显卡型号

yum install  nvidia-detect

Installed:

nvidia-detect.x86_64 0:384.90-1.el7.elrepo

nvidia-detect -v

Probing for supported NVIDIA devices...

[10de:134d] NVIDIA Corporation  GM108M [GeForce 940MX]

This device requires the current  384.98 NVIDIA driver kmod-nvidia

[8086:1916] Intel Corporation  HD Graphics 520

An Intel display controller was also detected

更新最新内核和内核开发文件

yum update  kernel kernel-devel

Installed:

  kernel.x86_64 0:3.10.0-514.21.1.el7 kernel-devel.x86_64 0:3.10.0-514.21.1.el7

查看内核数量

rpm -qa   kernel*

kernel-tools-3.10.0-693.5.2.el7.x86_64

kernel-3.10.0-693.5.2.el7.x86_64

kernel-devel-3.10.0-693.5.2.el7.x86_64

kernel-headers-3.10.0-693.5.2.el7.x86_64

kernel-tools-libs-3.10.0-693.5.2.el7.x86_64

删除多余的内核开发文件

yum  remove --nodeps    *****

启用默认版本内核

首先查看默认启动内核版本

uname -a

Linux THTF  3.10.0-693.2.2.el7.x86_64 #1 SMP Tue Sep 12 22:26:13 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

cat /boot/grub2/grub.cfg | grep  3.10.0-693.5.2.el7.x86_64

menuentry 'CentOS Linux (3.10.0-693.5.2.el7.x86_64) 7 (Core)' --class centos --class gnu-linux --class gnu --class os --unrestricted $menuentry_id_option 'gnulinux-3.10.0-693.el7.x86_64-advanced-e7d7b9e7-f593-4c29-b5db-4ccd7a7dc0d6' { 

 linux16 /vmlinuz- 3.10.0-693.5.2.el7.x86_64 root=/dev/mapper/vg_centos-lv_root ro rd.lvm.lv=vg_centos/lv_root rd.lvm.lv=vg_centos/lv_swap rhgb quietLANG=en_US.UTF-8

 initrd16 /initramfs- 3.10.0-693.5.2.el7.x86_64.img

设置默认内核（如果有多个内核）

grub2-set-default "CentOS Linux (3.10.0-693.5.2.el7.x86_64) 7 (Core) "

验证是否成功

grub2-editenv list

禁用nouveau驱动

lsmod | grep nouveau

nouveau 1527946 0

mxm_wmi 13021 1 nouveau

ttm 93908 1 nouveau

i2c_algo_bit 13413 2 i915,nouveau

drm_kms_helper 146456 2 i915,nouveau

drm 372540 8 ttm,i915,drm_kms_helper,nouveau

wmi 19070 2 mxm_wmi,nouveau

video 24400 2 i915,nouveau

i2c_core 40756 8 drm,i915,i2c_i801,i2c_hid,drm_kms_helper,i2c_algo_bit,nouveau,videodev

vi /lib/modprobe.d/dist-blacklist.conf

#blacklist nvidiafb

blacklist nouveau options nouveau modeset=0

更改grub2配置禁用nouveau

vi /etc/default/grub

GRUB_CMDLINE_LINUX="rd.lvm.lv=vg_centos/lv_root rd.lvm.lv=vg_centos/lv_swap rhgb quiet rdblacklist=nouveau"

重新生成grub.cfg

grub2-mkconfig -o /boot/grub2/grub.cfg

设置为文本模式启动

systemctl set-default multi-user.target

reboot

查看nouveau是否被禁用

lsmod | grep nouveau

输出空白，说明禁用成功

安装kmod-nvidia驱动

yum -y install kmod-nvidia

kmod-nvidia.x86_64 0: 384.98 -1.el7_4.elrepo 

nvidia-x11-drv.x86_64 0: 384.98 -1.el7.elrepo 

yum-plugin-nvidia.noarch 0:1.0.2-1.el7.elrepo

*如果安装不成功，有可能是没有配置/etc/X11/xorg.conf

nvidia-xconfig

重建内核initramfs image

备份initramfs image

mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bak

重建initramfs image

dracut /boot/initramfs-$(uname -r).img $(uname -r)

安装bumblebee

yum -y install bumblebee

bumblebee.x86_64 0:3.2.1-10.el7.elrepo 

VirtualGL.x86_64 0:2.3.3-4.el7.elrepo 

bumblebee-selinux.x86_64 0:1.0-1.el7.elrepo

fltk.x86_64 0:1.3.4-1.el7

kmod-bbswitch.x86_64 0:0.8-5.el7_4.elrepo

libbsd.x86_64 0:0.6.0-3.el7.elrepo

turbojpeg.x86_64 0:1.2.90-5.el7

把用户添加到 bumblee组

cat /etc/group | grep bumblebee

bumblebee:x:1001:

usermod  -a root   -G bumblebee

usermod  -a david -G bumblebee

cat /etc/group | grep bumblebee

bumblebee:x:1001:root,david

配置bumblebee.conf

vi  /etc/bumblebee/bumblebee.conf

[bumblebeed]

Driver = nvidia

[optirun]

Bridge= auto

[driver-nvidia]

KernelDriver= nvidia

PMMethod= bbswitch

LibraryPath= /usr/lib64/nvidia:/usr/lib64/vdpau:/usr/lib/nvidia:/usr/lib/vdpau

XorgModulePath= /usr/lib64/xorg/modules/extensions/nvidia,/usr/lib64/xorg/modules/drivers,/usr/lib64/xorg/modules

编辑nvidia-settings.desktop

vi /usr/share/applications/nvidia-settings.desktop

Exec=optirun nvidia-settings -c :8.0

设置图形模式启动

systemctl set-default  graphical.target

reboot

选择kmod-nvidia驱动关联的内核版本启动

测试是否安装成功

optirun  glxgears

optirun  glxspheres64

启动加载nvidia驱动

vi /boot/grub2/grub.cfg

在启动选项里，kernel那一条的后面追加   vga=792
