嗯，看来问题与 X.org 和 NVidia 有关，这与我遇到黑屏且键盘和鼠标无响应的情况一致。因此，我测试了 NVidia 网站上的建议：
https://forums.developer.nvidia.com/t/solved-suspend-resuming-and-wakeup-with-nvidia370-28/45282/9
但它并没有改变任何东西，所以我把配置恢复到初始状态。现在，我不知道如何解决这个问题。

有人能帮我解决这个问题吗？
答案1
我使用标准内核进行了测试，但问题仍然存在。因此，我卸载了专有驱动程序并使用 Nouveau。结果发现它解决了问题。此外，我测试了一些 3D 可视化代码，没有发现任何减速问题，也没有看到任何 CPU 过载——这些代码也进行一些数值计算，因此它们使用大量 CPU，因此如果有过载，我可能会看到过载。我还测试了视频编辑软件，同样，似乎显卡完全支持解码。此外，当专有驱动程序仍然不允许时，我可以使用 Wayland 代替 X.org。我尚未能够在显卡上测试计算。
当我的显卡还是新显卡时，Nouveau 的性能落后于专有驱动程序。现在显卡已经不是那么新了，Nouveau 的性能似乎可以与专有驱动程序的性能相媲美。
无论如何，我的观察是 NVidia 减慢了我们在图形服务器方面的进展。如果可以选择，我认为最好选择 ATI 处理器。如果您有 NVidia 处理器，如果它不是太新，那么值得尝试 Nouveau。
不管怎样，问题解决了。
