记录ubuntu安装nvidia-drivers简单的做法
开始安装
添加PPA，过程中回车确认询问的信息
sudo add-apt-repository ppa:graphics-drivers/ppa
依次执行以下命令更新下载源
sudo apt update
检查可用驱动
ubuntu-drivers devices
根据下列结果，可见 nvidia-driver-430 为推荐驱动安装版本
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001C07sv00001462sd00008C99bc03sc02i00

直接安装最新驱动，安装完成后重启电脑
sudo apt install nvidia-driver-430
重启后用命令 nvidia-smi 检查显卡是否被正常识别：显卡P106-100，显存6G，驱动430.26，CUDA10.2
