fedora系统安装nvidia驱动

安装nvidia驱动过程较为复杂，可参考如下：

安装完成后，重启启动，查看nvidia模块是否正常启动：
[root@guptest system]# lsmod |grep nvidia*
nvidia_uvm            888832  4
nvidia_drm             45056  0
nvidia_modeset       1089536  1 nvidia_drm
nvidia              14045184  482 nvidia_uvm,nvidia_modeset
ipmi_msghandler        57344  4 ipmi_devintf,ipmi_si,nvidia,ipmi_ssif
drm_kms_helper        196608  2 mgag200,nvidia_drm
drm                   458752  5 drm_kms_helper,mgag200,nvidia_drm,ttm

如果没有，需要创建启动脚本
/etc/rc.d/rc.local

#!/bin/bash

/sbin/modprobe nvidia

if [ "$?" -eq 0 ]; then
  # Count the number of NVIDIA controllers found.
  NVDEVS=`lspci | grep -i NVIDIA`
  N3D=`echo "$NVDEVS" | grep "3D controller" | wc -l`
  NVGA=`echo "$NVDEVS" | grep "VGA compatible controller" | wc -l`

  N=`expr $N3D + $NVGA - 1`
  for i in `seq 0 $N`; do
    mknod -m 666 /dev/nvidia$i c 195 $i
  done

  mknod -m 666 /dev/nvidiactl c 195 255

else
  exit 1
fi

/sbin/modprobe nvidia-uvm

if [ "$?" -eq 0 ]; then
  # Find out the major device number used by the nvidia-uvm driver
  D=`grep nvidia-uvm /proc/devices | awk '{print $1}'`

  mknod -m 666 /dev/nvidia-uvm c $D 0
else
  exit 1
fi

修改/lib/systemd/system/rc-local.service，增加内容如下：
[Install]
WantedBy=multi-user.target

执行如下命令;
systemctl enable rc-local.service
