其实Debian的non-free固件中包含NVIDIA的显卡驱动，所以没必要在官网下run包一步一步来

sudo apt install nvidia-settings

安装时会提示与X冲突，没关系，确认，安装完重启就好了

CUDA这些东西其实也都有

apt list nvidia*

就可以看到有哪些了，Linux装驱动也还是很简单的

我用的是USTC（中科大）的源，包含non-free包的源都是可以的

deb https://mirrors.ustc.edu.cn/debian/ buster main contrib non-free
deb-src https://mirrors.ustc.edu.cn/debian/ buster main contrib non-free

deb https://mirrors.ustc.edu.cn/debian/ buster-updates main contrib non-free
deb-src https://mirrors.ustc.edu.cn/debian/ buster-updates main contrib non-free
