还是看官方文档做吧
https://pkgs.org/download/nvidia-prime
得切换 nvidia卡
prime-select nvidia
This operation requires root privileges
admin@debian:~$ sudo prime-select nvidia
[sudo] admin 的密码：
Info: the nvidia profile is already set
glxinfo | grep OpenGL
bash: glxinfo：未找到命令
sudo apt-get install mesa-utils
驱动安装完以后，x进不去。我试试把xorg.conf做了备份，然后删掉，反正这个文件是安装驱动的时候创建的，debian本来就没有，桌面能进去了。

nvidia-settings

估计 驱动还是没装好。
glxinfo | grep OpenGL

OpenGL shading language version 是 1.30 ，这人家一般都是4.0以上了，驱动肯定没装好了。
我再试试。
linux-headers-$ 这个不安装的话，执行run会报错，还是sudo apt install nvidia-settings安装好一点。
sudo apt-get remove nvidia*
sudo apt-get autoremove
sudo apt-get update
sudo apt-get install dkms build-essential linux-headers-$(uname -r)
