问题： 似乎是随机的，并且在过去 2-3 个月中比前一年更频繁地出现所有程序退出并且系统返回到登录提示。
用户看到的只是黑屏。只有通过查看系统日志，我才发现 Xserver 崩溃了。这会触发转储所有程序，然后注销用户。
发生事件后，我登录后立即保存了 /var/log 中的所有内容。 这件事也发生在大约一小时前。
询问： 我没有太多经验来诊断导致这种情况的原因。非常感谢大家提供的任何意见。
我到目前为止尝试过的： 由于这个问题是在我们录制 OBS 视频到磁盘时出现的，我首先想到的是 CPU 超载。当时我们将录制质量改为全高清。崩溃后，我发现录制时 CPU 的使用率高达 98/99%，所以我觉得很容易达到最大值并崩溃。所以我将录制质量降低了几个档次。现在录制时，CPU 百分比保持在 75% 以下，通常在 60% 左右。
然后今天它崩溃了两次当我没有录制时，我想有一次 OBS 甚至没有运行！我的 CPU % 理论就到此为止了。
所以我抓取了整个 /var/log 文件夹。（复制到我的远程桌面）并查看了 Syslog。日志的最后 2 分钟看起来像是某个东西的重复循环。但在时间线的“开始”处，我发现了以下内容：

这似乎是从一个有趣的错误开始的：GPU 挂起：Xorg 中的 ecode 9：1：85dffffb [121129]
它还提到查看 X11 日志“/home/camera/.local/share/xorg/Xorg.1.log”：我没在这个文件中看到任何错误。主要是这个错误重复了几次。

我认为这是由于英特尔 CPU 因温度升高而降速所致。我发布了更多详细信息。

我正在测试的修复方法是安装一个 GNOME 插件，该插件允许您设置最小和最大 CPU 速度。默认设置是让 CPU 速度降低到 20%。我将其改为 90%。到目前为止一切顺利。我需要一个炎热的天气来找出这个想法是否有“陷阱”。
