尝试安装 GPU 驱动程序时遇到问题。
我安装了 495 NVIDIA 驱动程序。这是 Ubuntu 推荐的驱动程序。
不知何故，nvidia-smi 找不到我安装的驱动程序。然而，运行 DKMS 状态时，该驱动程序存在：
user@server:~$ 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.
user@server:~$ dkms status
nvidia, 495.29.05, 5.11.0-41-generic, x86_64: installed
user@server:~$ nvidia-debugdump -l
Error: nvmlInit(): Driver Not Loaded
user@server:~$ lspci -v | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation TU106 [GeForce RTX 2060 Rev. A] (rev a1) (prog-if 00 [VGA controller])
我也得到了这个：
user@server:~$ systemctl status nvidia-persistenced.service
● nvidia-persistenced.service - NVIDIA Persistence Daemon
Loaded: loaded (/lib/systemd/system/nvidia-persistenced.service; enabled; vendor preset: enabled)

Dec 06 14:50:17 server systemd[1]: nvidia-persistenced.service: Failed with result 'exit-code'.
Dec 06 14:50:17 server systemd[1]: Failed to start NVIDIA Persistence Daemon.
我的 GPU 被检测到了。我是否缺少将 nvidia-smi 链接到 Ubuntu NVIDIA 驱动程序所需的步骤？
我有一个xorg.conf文件，可以设置分辨率大小，但不能将其连接到 nvidia-smi。
如果您需要有关此问题的更多信息，请告诉我。
先感谢您。

这是sudo lshw -c video
user@server:~$ sudo lshw -c video

正如 heynnema 所说，
我在我的 UEFI bios 中禁用了安全启动。nvidia-smi现在运行良好！
user@server:~$ nvidia-smi
