我有一台配备以下 GPU 的 GP66 Leopard：
anto@anto-GP66-Leopard-11UH:~$ lspci | grep -i nvidia
01:00.0 VGA compatible controller: NVIDIA Corporation GA104M [GeForce RTX 3080 Mobile / Max-Q 8GB/16GB] (rev a1)
01:00.1 Audio device: NVIDIA Corporation GA104 High Definition Audio Controller (rev a1)
根据NVDIA 文档。
我的ubuntu版本支持CUDA开发工具：
anto@anto-GP66-Leopard-11UH:~$ uname -m && cat /etc/*release

我不知道我是否有正确的标题和开发包：
anto@anto-GP66-Leopard-11UH:~$ uname -r
5.11.0-40-generic
但我安装了最新的 Nvidia 驱动程序：
anto@anto-GP66-Leopard-11UH:~$ apt list --installed 'nvidia*'
Listing... Done
nvidia-container-toolkit/now 1.6.0-1 amd64 [installed,local]
nvidia-docker2/now 2.7.0-1 all [installed,local]
nvidia-utils-460-server/focal-updates,now 460.106.00-0ubuntu0.20.04.1 amd64 [installed]
但当我验证安装时
anto@anto-GP66-Leopard-11UH:~$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
那么，如何让 GeForce RTX 3080 Mobile / Max-Q 8GB/16GB 与 NVIDIA 驱动程序通信

答案1
实际上，您没有安装正确的专有 Nvidia 驱动程序。
正在使用的驱动程序显示在lspci -k输出中 -“正在使用的内核驱动程序：nouveau”。
首次运行sudo apt-get update时，您可以使用以下方法之一：
使用
nvidia-drivers工具自动安装sudo ubuntu-drivers autoinstall使用 GUI 安装驱动程序 - 启动软件和更新（
software-properties-gtk）并从安装 Nvidia 驱动程序附加驱动程序标签使用强力手段安装最新的 470 :)
sudo apt-get install nvidia*470 cuda*470 nvidia-cuda-toolkit
然后重新启动。
请注意，apt search nvidia-driver将显示搜索结果列表，而不仅仅是已安装的软件包（已安装的软件包标记为... now ... [installed]，但很难找到）。
要获取已安装软件包的列表，您必须使用apt list --installed 'nvidia*'或dpkg -l | grep -i nvidia。
