#KillUserProcesses=no
#KillOnlyUsers=
#KillExcludeUsers=root
#InhibitDelayMaxSec=5
#HandlePowerKey=poweroff
#HandleSuspendKey=suspend
#HandleHibernateKey=hibernate
HandleLidSwitch=lock

很多地方看的是system!!到处抄;这里是Centos7.2!在systemd目录!!!

#HandlePowerKey按下电源键后的行为，默认power off
#HandleSleepKey 按下挂起键后的行为，默认suspend
#HandleHibernateKey 按下休眠键后的行为，默认hibernate
#HandleLidSwitch 合上笔记本盖后的行为，默认suspend   （改为lock；即合盖不休眠）在原文件中，还要去掉前面的#

运行：

#systemctl restart systemd-logind

生效。
