系统崩溃，我被迫通过电源按钮关机。
我最近安装了Ubuntu 20.04大约 1 周前，因为我想尝试一下，暂时忘掉 Windows，但由于这些冻结，我无法做到。此外，当我关闭系统时，它永远不会关闭。
通常，这个问题在我观看视频时更常发生，但有时在导航时也会发生。我尝试使用一些工具来修复/修复/启动，我还增加了交换大小并更新了所有内容，但似乎没有什么可以解决这个问题。
如果有人能帮我解决这个问题，我将不胜感激。此外，当我尝试关闭系统时，它也会崩溃，并且永远不会自动关闭。

PD：我重新安装了 Ubuntu 20.04，但问题仍然存在。我还尝试只使用 iGPU 而不是专用 GPU，除了无限关机外，其他错误都消失了。
