为什么我的屏幕会冻结？

最近，我的 22.04 安装开始以特定方式冻结：

  1. 屏幕冻结；
  2. 键盘输入似乎没有任何作用；
  3. 但计算机仍在工作。

我知道3这是真的，因为我在 Zoom 通话时遇到过这种情况；通话继续进行，我可以听到人们说话的声音，但是，正如我所说的，屏幕冻结了，我用键盘进行的任何操作（例如++ Ctrl）都没有任何反应。AltF1

我升级到 23.04 但问题仍然存在。

我在系统冻结之前检查过系统日志，但是无法从中找出发生了什么。

问题答案：

  1. 我没有更改默认图形驱动程序。
  2. 我的内核是6.2.xxx。

更新：

我认为这与 Firefox 有关。我插入了一个新的下面的日志（由于字数问题，删除了旧的日志）立即地打开 Firefox 后。

答案1

不幸的是，日志没有给出问题根源的任何明确指示。

此问题通常是由不稳定的图形驱动程序引起的。乱用图形驱动程序可能会损坏您的操作系统（因此请先备份！），但您可以尝试转到 Ubuntu 中的“其他驱动程序”应用程序并尝试其他驱动程序。如果这些不起作用，您也可以直接从制造商处安装驱动程序（如果他们提供）。

此问题也可能是由内存 (RAM) 损坏引起的，但如果发生这种情况，我不希望 zoom 等继续工作。您可以使用 memtest86+ 之类的工具来测试这一点。
