当 Ubuntu 即将进入睡眠模式时如何发出警告（噪音/哔哔声）？

Question

我的睡眠模式时间很短。我喜欢这种方式……（大约 20 分钟）。

闲置 20 分钟后，我的系统将进入自动睡眠模式，我需要按下键盘才能重新激活。

当 Ubuntu 即将进入睡眠模式时，有没有办法发出噪音/哔哔声？

我确实收到了带有文字的通知警告，但我经常不看屏幕。

由于 NotifyOSD 团队正在花时间为通知添加声音，这里有一个脚本可以完成相同的任务，足以满足您的特定使用情况。
_{（它只会在系统进入睡眠状态时发出哔声通知您，恐怕所有通知都不会发出哔声……）}

1. 复制粘贴以下脚本：

   #!/bin/bash
   
   #
   # This script plays a sound if the system is going into hibernation/sleep mode
   # as an answer to http://askubuntu.com/questions/552999/how-to-warn-noise-bleep-when-ubuntu-is-about-to-go-into-sleep-mode/553026
   # Original script name: /etc/pm/sleep.d/sleep-beep
   #

   case $1 in
     suspend|suspend_hybrid|hibernate)
       notify-send --urgency=NORMAL --icon=face-tired "Going to sleep"
       ogg123 /usr/share/sounds/ubuntu/stereo/desktop-login.ogg
     ;;
   
     resume|thaw)
       # No need to do anything here, but easy to add if needed
     ;;
   
   esac
   

2. 进入gedit

3. 将其保存sleep-beep为你的 Documents 目录
4. 按Ctrl+ Alt+T进入终端

5. 使脚本可执行，然后将其复制到正确的目录：

   sudo chmod +x ~/Documents/sleep-beep
   sudo cp ~/Documents/sleep-beep /etc/pm/sleep.d/sleep-beep
   

6. 由于它需要从命令行播放 ogg 文件，因此它还需要：

   sudo apt-get install vorbis-tools
   

完毕！ ：-）
