Comment 1 for bug 1413865

the default setting for "when power is critically low" in power settings is "suspend",but it can't be setted to "suspended"(i don't know the reason), you can input command: gsettings set org.gnome.settings-daemon.plugins.power critical-battery-action "shutdown",we can set the default setting in package of gnome-settings-daemon.

笔记本默认设置为“休眠”，但是系统安装在本子上“休眠”选项不可选，所以这项就变成空白了，只要将gsetting的设置改为“shutdown”电源关闭就可以了，这个默认设置被集成在gnome-settings-daemon里面。改一下然后安装应该就可以了
