ubuntu 18.04 关闭合盖休眠

编辑下列文件：/etc/systemd/logind.conf

• 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ignore；即合盖不休眠）在原文件中，还要去掉前面的#

然后将其中的：

• HandleLidSwitch=suspend
• 改成下面，记得去掉“#”号：
• HandleLidSwitch=ignore

注：在Ubuntu18.04和Ubuntu16.04笔记本电脑，下面测试可以使用。

运行：systemctl restart systemd-logind就会生效。
