我看到很多类似的问题，但是：
- 它们非常老了（2012-2014）
- 他们说它根本不起作用
相反，我的问题有所不同。我在 PC 桌面上运行 Ubuntu 20.04，规格如下：
$ lshw -short -quiet

我配置了电源按钮以进入挂起模式。它工作了将近一年。我每天都会使用此功能几次。
几个月以来，我有时会再次按下按钮从挂起模式恢复，PC 会唤醒（我听到风扇噪音），但屏幕仍然黑着，什么也没发生。我只能按下重置按钮或按住电源按钮才能恢复正常。
最近，这个问题出现得越来越频繁。
因为它一天比一天糟糕，所以我认为这与更新或特定事件/设置无关。
但我没有足够的知识来了解发生了什么以及如何解决。
