启动并登录后，我可以调用journalctl并查看盖子开关事件：
# journalctl | grep -a "Lid"
Mar 22 09:18:19 debian kernel: input: Lid Switch as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0D:00/input/input2
Mar 22 09:18:19 debian kernel: ACPI: Lid Switch [LID0]
Mar 22 09:18:20 debian systemd-logind[599]: Watching system buttons on /dev/input/event1 (Lid Switch)
但是，如果我打开和关闭笔记本电脑的盖子，无论我多久这样做一次，输出中都不会添加任何内容。盖子操作不会在 中记录任何进一步的条目journalctl。因此，当我合上盖子时，我的屏幕会保持打开状态。
是什么原因造成的？我该如何修复它？
