第一步：查看显卡类型
[root@localhost ~]# lshw -numeric -C display
显示显卡类型：product: GK107 [GeForce GTX 650] [10DE:FC6]
显示驱动是nouveau：configuration: driver=nouveau latency=0
Nouveau是第三方为NVIDIA显卡开发的一个开源3D驱动，没有得到NVIDIA的认可与支持。
第二步：到nvidia官网下载对应驱动 https://www.nvidia.com/Download/index.aspx#
NVIDIA-Linux-x86_64-440.44.run
第三步：安装驱动所依赖的软件包
# yum groupinstall "Development Tools"
# yum install kernel-devel epel-release
# yum install dkms
第四步：禁用nouveau,通过修改配置 /etc/default/grub
[root@localhost ~]# vi /etc/default/grub
原来的设置
1 GRUB_TIMEOUT=5 2 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" 3 GRUB_DEFAULT=saved 4 GRUB_DISABLE_SUBMENU=true 5 GRUB_TERMINAL_OUTPUT="console" 6 GRUB_CMDLINE_LINUX="crashkernel=auto resume=/dev/mapper/cl-swap rd.lvm.lv=cl/root rd.lvm.lv=cl/swap rhgb quiet" 7 GRUB_DISABLE_RECOVERY="true" 8 GRUB_ENABLE_BLSCFG=true
新的设置
1 GRUB_TIMEOUT=5 2 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" 3 GRUB_DEFAULT=saved 4 GRUB_DISABLE_SUBMENU=true 5 GRUB_TERMINAL_OUTPUT="console" 6 GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet nouveau.modeset=0" 7 GRUB_DISABLE_RECOVERY="true" 8 GRUB_ENABLE_BLSCFG=true
执行
grub2-mkconfig -o /boot/grub2/grub.cfg
grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg
使配置生效
[root@localhost ~]# grub2-mkconfig -o /boot/grub2/grub.cfg Generating grub configuration file ... Adding boot menu entry for EFI firmware configuration done [root@localhost ~]# grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg Generating grub configuration file ... Adding boot menu entry for EFI firmware configuration done
第五步：重启centos，确认配置生效，nouveau不再使用
[root@localhost ~]# lshw -numeric -C display *-display UNCLAIMED description: VGA compatible controller product: GK107 [GeForce GTX 650] [10DE:FC6] vendor: NVIDIA Corporation [10DE] physical id: 0 bus info: pci@0000:02:00.0 version: a1 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list configuration: latency=0 resources: memory:fa000000-faffffff memory:e0000000-efffffff memory:f0000000-f1ffffff ioport:e000(size=128) memory:c0000-dffff
第六步：安装Nvidia驱动时，必须停止Xorg服务，转成text模式
[root@localhost ~]# systemctl isolate multi-user.target
第七步：安装，运行命令：bash NVIDIA-Linux-x86_64-440.44.run，一路yes
[root@localhost ~]# ls

第八步：重启后，进入终端运行：nvidia-settings
进入 NVIDIA X Server Settings
