由于有两台电脑，四个显示器，在使用的时候，难免要切换，但笔记本的触控板和键盘实在太难用～%>_<% 但是机械键盘和鼠标只有一套，怎么办呢？
还好之前看一些大牛的工作环境时，看到有一个工具叫synergy，用来同步鼠标和键盘，可以随意在多台电脑中切换。

通过apt-get 安装

因为我常用的操作系统是ubuntu和kali，当然是直接apt-get。

apt-get install synergy

安装后，两台ubuntu（synergy版本1.4.12）之间操作没问题，然而在kali上是1.4.16版本，有不兼容的问题。于是找了下源，并没有找到对应的仓库，干脆就两边使用最新的源码install好了。

通过源码安装

首先，安装依赖

sudo apt-get install cmake make g++ xorg-dev libqt4-dev libcurl4-openssl-dev libavahi-compat-libdnssd-dev libssl-dev

访问synergy on github，git clone或者直接下载，然后：

tar xzvf v1.7.5-stable.tar.gz
cd synergy-1.7.5-stable
./hm setup
./hm conf -g1
./hm build

搞定。kali上也是如此操作，因为也是基于Debian。

使用

跟着上面的操作，工作目录还在synergy-1.7.5-stable，执行bin/synergy

1，开启服务器（服务器即是你鼠标和键盘连接的那台电脑），synergy 会有个向导，选择服务器模式；
2，点击Configure Server，拖拽显示右上角的显示到格子中，想要的放置位置，这里要注意显示器的name需要填写正确，这个name就是client（或server）的名称，client若对不上，会被server拒绝连接的（name在Edit - Settings中设置）。

3，主界面点击start，界面可以看到log，包括客户端的连接。
4，启动server后，其他主机同样bin/synergy启动，选择client模式，接着设置一下自己的name，填写server的IP，点击Start。
5，Okay，这时可以发现，一套键鼠可以操控多台计算机啦，尽情地享受多屏多机的快感吧，工作效率杠杠的。 :-D
