更新：值得注意的是，这是英特尔 i5 第 10 代 CPU。
我最近购买了一台新的 Lenovo ThinkPad Carbon x1（第 8 代）并在其中安装了 Debian Buster。安装所有最新的软件包并进行固件升级（也从非免费版本升级）后，我意识到我在 Firefox 甚至 urxvt 中遇到短暂的冻结，持续 0.5 秒到 10 秒，这意味着显示屏停止更新（键盘挂起后鼠标输入可见）。
可以立即更改 TTY，并且可以解冻屏幕。 dmesg 或 Xorg.0.log 甚至journalctl 中都没有相关日志。我的意思是，在发生这些挂起的特定时间，我们根本没有编写任何日志。我的系统上有大量可用内存 (16GB) 和大量交换空间 (也是 16GB)。这些在一分钟内发生很多次，当我使用 Firefox 时甚至更多（我认为）。
有任何想法吗？提前致谢！

答案1
我也看到这是一个 i7 运行破坏者。 AFYI 如果我有音频运行，声音不会中断。如果我让 glxgears 保持运行，它会冻结，但控制台日志显示速率不变，为 3pfps（这是 4K 显示器）。
我已经运行巴斯特好几年了。这种行为是相对最近的（可能是几个月）。和你一样，我使用 Xorg（不是 wayland），但也使用 cinnamon 和 lightdm。
所以我相信，图形的更新只是冻结了，动作仍在继续（即，如果您移动鼠标、拖动窗口等，它们会发生，但几秒钟内不会显示在屏幕上）......这非常令人沮丧
