Ubuntu 20.04 在启动过程中非确定性地挂起

我在使用新笔记本电脑和全新安装的 Ubuntu 时遇到了问题。在启动过程中，大约有 30-40% 的时间，笔记本电脑会冻结并出现黑屏。我尝试让它静置 10 分钟以上，但没有明显效果。我已经能够重现此问题

  1. 在 grub 中禁用启动画面后
  2. 是否插入显示器
  3. 我尝试使用 运行nomodeset，但在这种情况下没有检测到故障。但是，我无法连接到外部显示器。也可能我没有检测到故障，只是因为我没有尝试运行nomodeset超过几分钟（由于显示器问题）。

似乎发生了后ubuntu 的各个部分都已初始化。特别是，从 grub 的选项中删除 quiet 后，它将运行启动顺序，并在从滚动启动日志转换到登录屏幕时冻结。我似乎也无法切换到终端，因此很难准确调试冻结的位置。但是，一旦笔记本电脑启动，我就不会发现任何问题！

正如标题所述，这是使用 Ubuntu 20.04。笔记本电脑本身是 ThinkPad（t495，型号 20NK），输出如下lspci

我没有特意安装任何驱动程序或做任何事情来修改标准的 Ubuntu 安装（尽管我在安装过程中确实允许使用专有驱动程序），但如果我应该在这里添加任何其他信息，请告诉我。

答案1

好吧，虽然这不是一个确定的答案，但似乎这种行为是这张未结票。至关重要的是，该线程指出这些问题似乎仅在使用电池供电时才会发生，这与我的情况相符。

其中提出了几种解决方法，并提到这个问题似乎在比 20.04 更新的内核版本中得到了解决。

我的解决方案是始终使用电池电源启动并等待内核更新，因为它似乎正在筹备中。
