挂起功能过去在我的笔记本电脑上运行得很好，但自从最近的更新以来我遇到了一个问题。将笔记本电脑从挂起状态唤醒后，屏幕不亮。其他一切似乎开机正常，但屏幕上没有图像。笔记本电脑已完全唤醒，但屏幕上没有图像。然而，我发现了一个“修复”。如果我唤醒了笔记本电脑，并且面对黑屏，我可以使用 HDMI 电缆将其唤醒。我要做的就是插入一根 HDMI 电缆（例如，连接到电视的一根），只需插入它的动作就会“唤醒”屏幕。这很奇怪，但很有效。当然，问题是我无法随身携带电视，所以这不是一个永久的解决方案。
这是更多调试代码。

我之前使用的是最新的内核，但是出现这个问题后将其更改为LTS：
$ uname -a Linux george 4.14.34-1-lts #1 SMP Thu Apr 12 20:30:09 CEST 2018 x86_64 GNU/Linux
有人知道这是什么吗？
我使用 i3 作为窗口管理器，无桌面环境，Arch Linux 操作系统。
