我在 Ubuntu 18.04.1 LTS 台式机上安装了 NVIDIA 390.77。我有一个专用的 NVIDIA GPU，我想在其上运行模拟程序（例如 Gazbeo），使用 GPU 渲染视觉输出。它在之前安装的 Ubuntu 16 上运行良好，其中 nvidia-smi 显示了 GPU 进程之间的进程。在新安装的 Ubuntu 18 上并非如此。
运行 nvidia-settings 似乎也存在问题（参见最后一段代码）。我不太明白哪里出了问题，因为有两个进程作为 gpu 进程运行……
据我所知，我不需要任何卸载，因为我只有一个 GPU。
我希望实现的目标：
1.) 让模拟客户端（gzclient）使用 GPU 进行渲染。2.) 运行 nvidia-settings。
非常感谢任何帮助。

nvidia-smi 的输出看起来不错。甚至有 2 个 GPU 进程正在运行：
