如何在 ubuntu 20.04（服务器）启动时启用 nvidia 持久模式

Question

每次我尝试调用nvidia-smi它都需要很长时间才能显示；事实证明应该启用持久模式，一种简单的方法就是调用nvidia-smi -pm 1. 但这并不能使其启动。

我怎样才能让它在启动时工作？我尝试运行sudo nvidia-persistenced，但系统日志如下：

 kernel: [  949.165626] NVRM: Persistence mode is deprecated and will be removed in a future release. Please use nvidia-persistenced instead.

Answer 1

nvidia-driver-$version从默认 Ubuntu 存储库安装软件包。它将安装 nvidia 驱动程序、nvidia-persistenced二进制文件，并启动nvidia-persistenced.servicevia systemd。

跑步：

systemctl edit nvidia-persistenced.service

这将创建一个覆盖文件来更改默认文件的行为/lib/systemd/system/nvidia-persistenced.service。这将打开默认编辑器，很可能nano其中没有任何内容。粘贴以下内容：

[Service]
ExecStart=
ExecStart=/usr/bin/nvidia-persistenced --user nvidia-persistenced --persistence-mode --verbose

保存文件，它将自动创建为/etc/systemd/system/nvidia-persistenced.service.d/override.conf. 最后，重新启动守护进程：

systemctl restart nvidia-persistenced.service
