我的 Ubuntu 19.04 电脑（Ubuntu 18 也发生过这种情况）意外冻结，键盘和鼠标停止工作，如果我重新启动显示器，它们不会记录任何输入。我唯一能做的就是按住电源按钮 5 秒钟，直到它关闭，然后重新启动。我与 Windows 有双启动，如果这有某种相关性的话，它可以正常工作。
上次发生这种情况时，每秒都会记录一次，持续 2 分钟，直到冻结。

所以我想问一下，可能是什么问题以及如何解决？

可能不只是 19.04，我的 18.04 也变得不稳定，我的多显示屏变黑，主屏幕保持打开状态，但所有内容都被锁定了
这个系统通常一次运行数月都没有问题，今天我不得不强制重启它十几次，自从我让它重启以来，因为几个月来已经应用了相当多的更新..它运行内核 5.1 有一段时间了，所以我不认为是那样..

系统日志中出现随机错误，这可能是重启前的最后一个错误
