![睡眠后黑屏:热插拔事件:连接器链接状态为 BAD](https://linux22.com/image/136554/%E7%9D%A1%E7%9C%A0%E5%90%8E%E9%BB%91%E5%B1%8F%EF%BC%9A%E7%83%AD%E6%8F%92%E6%8B%94%E4%BA%8B%E4%BB%B6%EF%BC%9A%E8%BF%9E%E6%8E%A5%E5%99%A8%E9%93%BE%E6%8E%A5%E7%8A%B6%E6%80%81%E4%B8%BA%20BAD.png)
过去,我的笔记本电脑运行良好,但在过去的几个月里,我遇到了笔记本电脑屏幕在某些事件后无法唤醒的问题。基本上,在我暂停笔记本电脑后,估计有 15% 的时间唤醒机器后屏幕不会打开。当屏幕在一段时间不活动后变黑时,会出现类似百分比的空白屏幕。当我移动鼠标时,它可能会也可能不会再次唤醒。
我回顾了其中一个情况,其中屏幕因非活动而变黑后无法打开(因为日志条目比挂起时少)。在屏幕变黑并且我再次移动鼠标期间,没有journalctl条目。但是,在 xorg 日志中我发现了这一点(我无法破译时间戳,但这是日志文件的末尾):

我能找到的唯一相关主题是:https://bbs.archlinux.org/viewtopic.php?id=236359——但是里面没有解决方案。我已经使我的系统保持最新状态。使用 i3 作为窗口管理器运行 Arch Linux。我的内核是 4.14.52-1-lts。有什么想法可能是什么原因造成的吗?
