Ubuntu系统18.04更新驱动解决方法

原始是：ubuntu18.04里面的驱动是470，对应cuda11.4
现在需要更新为525，对应cuda为12.0

实现：
1、打开终端

Ctrl + Alt + T

2、使用 lspci 命令（快速查看显卡型号）

lspci | grep -i vga

3、终端输入

ubuntu-drivers devices

解决办法
终端提示推荐下载nvidia-driver-525

终端输入：

sudo apt install nvidia-driver-525

经过一系列的处理之后，安装完成后，重启系统使驱动生效：

sudo reboot

重启之后，验证驱动是否安装成功

nvidia-smi
