当前正在运行的内核是5.4.0-29-generic。当我查看 时htop，我看到的Xorg是顶部的。
Launchpad 错误 #1861294（Gpu 看门狗段错误和 optiplex 7060 intel gpu 上的视频+kbd+鼠标冻结）看起来很相似。虽然第一份报告是针对英特尔 GPU 的。相似之处在于GpuWatchdog段错误，有趣的是还提到了 Slack，它甚至在我的内核堆栈跟踪中，但不确定这是否相关。
Unix SE 562458（Google Chrome 中的段错误 - 与 Nvidia 卡有关吗？我如何查找？）看起来也颇有关联。
现在，使用较新的内核（Linux az-Desktop2020 5.4.0-33-generic #37-Ubuntu SMP Thu May 21 12:53:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux），我再次遇到了另一个奇怪的冻结（或者没有完全冻结，它仍然有响应，但速度太慢以至于无法使用）。XorgCPU 使用率为 99%。 我杀死了Xorg，Ubuntu 自动启动了一个新的 Xorg 实例，该实例再次具有 99% 的 CPU 使用率，但现在屏幕保持黑色（也许我只需要等待几个小时，它就会非常缓慢地返回桌面……）。
dmesg告诉我这个，这可能有关，但我不确定（这些消息很旧；今天是星期二......）

再次。桌面大部分（但不是完全）冻结，即我几乎无法移动鼠标，点击时甚至有一些反应，但速度非常慢（真的无法使用）。我仍然可以通过 SSH 访问它（基本上一切都通过 SSH 正常运行）。这是在我从睡眠模式唤醒 PC 后发生的。

完整日志这里。这次，崩溃似乎发生在spotify。但这可能是由之前的 NVRM 错误引起的。
我刚刚了解到Nvidia Xid 错误。
此错误报告（nvidia-graphics-drivers-435 包：Nvidia 驱动程序崩溃后桌面冻结 30 秒）聽到有關的。
Pid 1924（来自 Xid 错误 31）：
