驱动从 460.91.03，升级到470.103.01,需要恢复
1输入下条命令，卸载电脑驱动

sudo apt-get purge nvidia*

2输入下条命令，把显卡驱动加入ppa（个人软件包文档，仅支持Ubuntu），类似于应用商店

sudo add-apt-repository ppa:graphics-drivers
sudo apt-get update
3使用以下命令查看系统版本库中所有nvidia驱动的信息，根据需要选择合适的版本。

$ sudo apt-cache search nvidia
4推荐使用以下命令，查看Ubuntu推荐的驱动版本，从中选择合适的版本。

ubuntu-drivers devices

5显卡的安装

在版本库中选择推荐的驱动版本进行安装。如选择nvidia-driver-460进行安装。

$ sudo apt install nvidia-driver-460 nvidia-settings nvidia-prime

6.重启
sudo reboot

7.输入下条命令，查看解决方案是否生效
