Ubuntu 20.10冻结

Question

昨天，我的带有Ubuntu的台式机(而不是笔记本)冻结了3到4次(冻结了一分钟左右，然后像以前一样继续工作)。这就是我在日志中看到的：

我现在正在谷歌，试图了解它是关于什么，但也许这里的人将能够帮助我了解什么是冻结的来源。

桌面使用Ryzen 53600(如果这重要的话)。

掉期计划正在进行：

cat /proc/swaps
Filename                Type        Size        Used        Priority
/swapfile                               file        4194300     0       -2

sudo journalctl给出了我在这里发布的相同的结果(相同的错误，相同的细节)。

解出 I通过更换显卡解决了一个问题。最初是NVidia GeForce 210 (是的，当时我有一张最简单的卡)。它在正确检测我的显示器方面有问题，所以我从NVidia 340驱动程序切换到了新驱动程序，手动设置了2550x1440R模式)。它是有效的，但我想这张卡就是不能处理这样的解决方案，它导致了这些问题)。我用AMD RX 550取代了显卡，发行版消失了。谢谢你的评论。
