nvidia-smi 没有列出任何进程并且没有内存使用

Question

由于我在笔记本电脑（Asus Zephyrus-G-GU502DU-GA502DU）上安装了 Ubuntu，我在使用 nvidia 驱动程序时遇到了问题。由于 nvidia-smi 从未列出进程，因此我一直无法看到 GPU 是否真正被使用。

这是 nvidia-smi 的输出：

这是 nvidia-settings 的输出：

一些注意事项：

• 电池耗尽非常快。它从未持续超过3小时。正常情况下会比这少。
• 一直都是这样。我已经尝试过 Ubuntu 18.04、19.04 和现在的 19.10。
• 从休眠状态打开/关闭需要一些时间。

Answer 1

我感觉到你了，伙计。我有同样的笔记本电脑和同样的问题，需要一段时间才能找到针对 AMD/NVIDIA 组合的开箱即用解决方案。不要失去希望。:-)

与此同时，对我有帮助的是从这里安装最新的 AMD 驱动程序：https ://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update && sudo apt upgrade

重新启动后，您将看到仅使用 AMD Radeon Vega 10 显卡，这将有助于减少电池消耗。然而，Ubuntu 19.10 感觉有点慢，这就是我现在切换到 Ubuntu MATE 的原因。一旦 Ubuntu（或 Manjaro）提供了正确的驱动程序，我将在这里切换并更新您。

希望这对您有一点帮助。
