Handle开头的
#HandlePowerKey=poweroff # 按下电源键后如何
#HandleSuspendKey=suspend # 待机挂起后如何
#HandleHibernateKey=hibernate # 按下休眠键后如何
#HandleLidSwitch=suspend # 合上笔记本盖后如何
#HandleLidSwitchDocked=ignore # 合上笔记本盖后外接显示器如何
可选的参数值
| 参数 |
说明 |
| ignore |
忽略，啥也不干 |
| power off |
关电源 |
| reboot |
重启 |
| halt |
挂起。停止所有的 CPU 功能，但是仍然保持通电。 |
| suspend |
待机 |
| hibernate |
进入休眠（内存数据存入硬盘，关闭电源） |
| hybrid-sleep |
混合睡眠=睡眠+休眠，主要是为台式机设计的，内存和CPU还是活的。 |
| lock |
锁屏，机器继续跑（相当于Win+L） |
其他选项
#LidSwitchIgnoreInhibited=yes # 合上笔记本盖子时是否应该忽略被某些应用程序所发出的“禁止休眠”的请求
- 当设置为
yes 时，无论如何都执行 HandleLidSwitch的定义，即无论应用程序发出任何关于系统状态控制请求，都不会被执行，而是以 HandleLidSwitch为准。
- 当设置为
no 时，不受 HandleLidSwitch约束。即如果有应用程序发出请求，要求在合盖时不进行休眠或其他操作，系统将不会执行 HandleLidSwitch 定义的行为。
修改配置
保存时要用 :wq
vim /etc/systemd/logind.conf
# 修改
HandleLidSwitch=lock
LidSwitchIgnoreInhibited=yes
注意： 我这边只需要合上笔记本盖后不休眠，请根据自己情况选择参数。
改完 cat 查看一下，确保无误。
