有一段时间，我的 Ubuntu 22.04.4 相当迟缓。
启动并登录后，桌面会冻结 10 - 20 秒；一开始是完全冻结，大约 5 秒后我可以移动光标，但无法与任何东西交互。之后，屏幕短暂地变灰，然后再次出现（我强烈假设 Gnome 正在重新启动）。我注意到一件有趣的事情是，桌面总是在 dock（左侧边栏）初始滑入动画完成之前冻结。
重新出现后，它总体运行正常，除了有些东西很慢/迟缓有时。问题并不一致。系统会慢一分钟或几分钟，然后可能会正常工作一个小时，然后再次变慢。很难准确计时，我也无法触发“缓慢”。
我最注意的是文本输入，尤其是在终端中，它明显延迟，或者有时单个按键，尤其是在开始输入时偶尔会完全错过。这种情况发生在常规终端、标准编辑器以及 PHPstorms 内置终端中。PHPstorm 的代码编辑器部分似乎没有受到影响，或者至少没有那么明显。
我还注意到有时（但比文本输入问题少得多）UI 的某些部分会闪烁。
一个例子是在文本编辑器中：按下回车键时，行会来回闪烁几次（转到下一行并返回当前行，2-3 次）。
另一个例子是突出显示的文本或行保持突出显示一段时间，即使在更改选择或行之后也是如此。输入时，突出显示会出现/消失几次，然后最终消失。
总体而言，这些问题似乎主要与文本输入有关。
这是在做了一段时间后开始的apt full-upgrade。以前，一切都很快，反应灵敏。
信息:
我原本以为我的问题可能类似于从 22.04.2 更新后，Ubuntu 22.04.4 运行非常慢但它们的 CPU 时钟速度似乎较低，而我的似乎不低。我还是在那里添加了所要求的信息，因为我真的不知道从哪里开始。如果有任何必要/有用的其他信息，请在评论中告诉我，我会添加它。

到目前为止我尝试过的事情
我试图录制一些故障和闪烁，但有趣的是，录制屏幕似乎可以避免它们。不过这可能只是巧合。我用简易屏幕录像机。
我/var/log/kern.log发现了很多与 docker 相关的消息。起初我以为它们可能会减慢系统速度，但在停止 docker 后，系统似乎一开始变得更快了。然后我尝试禁用 docker 自动启动并重新启动几次。起初我以为这解决了问题，因为系统正常启动并立即可用。但在 3-4 次重新启动后，问题再次出现，即使 docker 仍然被禁用。我不确定如何处理这些信息。这可能是 docker 出现问题的迹象，还是只是巧合？从那时起，系统每次启动时都会立即冻结。
偶尔/var/log/syslog会出现系统太慢的消息（可能是潜在问题的症状？）

我尝试查看其他一些日志文件一段时间，看看它们是否会被淹没。但我没有注意到任何特别大量的日志消息，以至于导致系统速度如此缓慢。
我检查了 Gaphics 驱动程序。过去，我遇到过使用 Nouveau 驱动程序时 GUI 速度慢的问题。根据lshw -c video所用的驱动程序仍然是 nvdia。我认为这不是问题所在，但我不能完全排除这种可能性。
我正在双重启动这台机器。在 Windows 上没有出现任何问题，所以我很确定这不是硬件故障。
导致此问题的原因是什么？我该如何解决此问题？
