使用 ubuntu-drivers 安装 nvida 显卡驱动的一些疑问？

Question

我在看这篇教程：如何在 Ubuntu 22.04 或 20.04 上安装 NVIDIA 驱动程序

里面提到使用 ubuntu-drivers devices 安装显卡驱动

─➤  ubuntu-drivers devices
== /sys/devices/pci0000:80/0000:80:03.0/0000:81:00.0/0000:82:08.0/0000:83:00.0 ==
modalias : pci:v000010DEd000013F2sv000010DEsd0000115Ebc03sc02i00
vendor   : NVIDIA Corporation
model    : GM204GL [Tesla M60]
driver   : nvidia-driver-418-server - distro non-free
driver   : nvidia-driver-510 - distro non-free
driver   : nvidia-driver-515-server - distro non-free
driver   : nvidia-driver-525 - distro non-free recommended
driver   : nvidia-driver-515 - distro non-free
driver   : nvidia-driver-390 - distro non-free
driver   : nvidia-driver-470 - distro non-free
driver   : nvidia-driver-450-server - distro non-free
driver   : nvidia-driver-525-server - distro non-free
driver   : nvidia-driver-470-server - distro non-free
driver   : xserver-xorg-video-nouveau - distro free builtin

我有一些疑问，比如这个 nvidia-driver-450-server - distro non-free 后面的 non-free 就是闭源驱动的意思吗？就是 nvidia 官方驱动？

然后就是输出了这么多驱动，我应该怎么选？选一个数字最大的 nvidia-driver-525-server - distro non-free 吗？

然后一个问题，当我使用 sudo apt install nvidia-driver-525-server 安装显卡驱动的时候，发现待安装的软件列表里面居然没有 nvidia-smi

这正常吗？chatgpt 说，安装了驱动，就应该有 nvidia-smi 命令的
