之前在这篇文章中写了如何在openSUSE上面启用混合休眠功能,当初在Ubuntu上面可以通过同样的方法启用混合休眠,今天发现在Ubuntu16.04上面就无法启用混合休眠,网上说是因为systemd和pm冲突.

经过一方努力我发现KDE的休眠按钮调用的systemd的休眠功能,systemd的休眠是通过systemd-hibernate进行休眠,systemd-suspend进行挂起操作,于是我们可以通过修改systemd的休眠服务把休眠功能替换成混合休眠.

打开/lib/systemd/system/systemd-hibernate.service

里面的内容是

[Unit]

Description=Hibernate

Documentation=man:systemd-suspend.service(8)

DefaultDependencies=no

Requires=sleep.target

After=sleep.target



[Service]

Type=oneshot

ExecStart=/lib/systemd/systemd-sleep hibernate

然后把里面的hibernate改成hybrid-sleep,

#  This file is part of systemd.

[Unit]

Description=Hibernate

Documentation=man:systemd-suspend.service(8)

DefaultDependencies=no

Requires=sleep.target

After=sleep.target



[Service]

Type=oneshot

ExecStart=/lib/systemd/systemd-sleep hybrid-sleep

然后保存就行了.

现在通过KDE按钮进行休眠就是混合休眠,通过终端执行pm-hibernate依旧是正常休眠.
