Ubuntu MATE 16.04 LTS 中的睡眠定时器暂停

Question 1

如果您不介意使用终端，您可以这样做。

执行：sleep 2h 45m 20s && systemctl suspend -i

它会在 2 小时 45 分钟 20 秒内暂停您的系统。

我编写了一个脚本来获得如下的 GUI：

复制以下脚本的内容并将其保存到您的主目录中 fast_suspend.sh。

#!/bin/bash

        else

此外，您还可以创建一个.desktop文件来运行它。

复制以下文本并将其保存为fast_suspend.desktop。

[Desktop Entry]
Type=Application
Terminal=false
Icon=
Name=fast_suspend
Exec=/home/your-user-name/fast_suspend.sh
Name[en_US]=fast_suspend

为两个文件提供执行权限-执行：

chmod a+x ~/fast_suspend.sh ~/Desktop/fast_suspend.desktop

当你想再次启动此窗口时，只需双击在fast_suspend桌面上。
