ubuntu下电脑合盖休眠设置

问题描述：希望ubuntu下电脑能够在合盖或者点击挂起时电脑是休眠状态，而不是直接关机，带来很多不便。通过自己查找的一些资料，发现以下办法基本上可以解决我的问题，希望能够对大家有帮助。
方法一：

方法一：
To make Ubuntu do nothing when laptop lid is closed:
1、Open the /etc/systemd/logind.conf file in a text editor as root, for example,
sudo -H gedit /etc/systemd/logind.conf

2、Add a line HandleLidSwitch=ignore (make sure it's not commented out!),
3、Restart the systemd daemon with this command:
sudo restart systemd-logind

or, from 15.04 onwards:
sudo service systemd-logind restart

方法二：

You can easily do it.
Edit /etc/systemd/logind.conf and set
HandleLidSwitch=hibernate
HandleSuspendKey=hibernate

You can also use hybrid-sleep instead of hibernate.
Don't forget to remove the # in front of the above two lines and also to reboot.
