我刚刚安装了 Ubuntu 20.04（大约 5 天前，所以安装得相当干净），当我通过浏览器使用 MS Teams 时，一开始运行正常，然后在会议开始大约 20 或 30 分钟后，我的整个操作系统 GUI 冻结了，我无法使用任何东西。
当我准备参加会议时，我进行了一次硬重启，试图重新进入会议，我这样做了，但后来它又崩溃了。这次我离开了，最终，大约 15 分钟后，出现了一个“抱歉，Ubuntu 20.04 遇到了内部错误”对话框，GUI 解冻了。
我已附加“全部”日志和“重要”日志，以及崩溃对话框的屏幕截图。
第二次崩溃（与这些日志相关）发生在 13:54。
任何能帮助我们隔离问题的方法都将不胜感激！谢谢。

答案1
我不太好意思告诉你这个，但你试过在 Ubuntu 上的 Microsoft Edge beta 中使用它吗？我和一些 Windows OS 上 Google Chrome 上的 Microsoft Teams 用户遇到过几次同样的问题。虽然不是在 Microsoft Edge (chromium) 中。
