一个新的贡献者──efeller，编写出了一个很酷的插件──smackpad。这个插件能让你的ThinkPad变成“SmackPad”。
什么是smackpad呢？让我们来看看。
首先说明，并非只有ThinkPad才能变成“SmackPad”，只要有HDAPS传感器的笔记本（如大多数ThinkPad系列， Toshiba和Apple MacBook (Pro)都有)，都可以安装这个插件。那么如何看自己的本本有没有HDAPS传感器呢？在终端下执行：
ls /sys/devices | grep hdaps
如果返回结果是存在，那么恭喜你。你的本本可以变成“SmackPad”！
说了那么多，还没有说smackpad是什么呢？
就是拍一下笔记本，就会切换一个虚拟桌面（同trl+Alt+左右键效果），COOL!!

可是我make 老是出错，怎么回事？
