（2）：下载vim

除了五笔外，ibus还有拼音，以及一些其它输入法.

添加好后保存，再输入 sudo apt-get update 就可以更新了，

等着慢慢下载东西吧。接着是：

sudo apt-get install vim

（3）：下载五笔

1:Ctrl+Alt+T 打开终端

2: 输入以下命令:

sudo apt-get install ibus ibus-table ibus-table-wubi

安装三个包：ibus,ibus-table ibus-table-wubi

3:打开System setting面板，点击language support,在Keyboard input method system右边的下拉框中选中ibus,退出

4：注销，再次进入系统，在右上角的就会多一个ibus的东东，点开下拉，选择Preference,打开ibus preference面板，

选择Input Method选项卡，选择想要的输入法，然后点击Add按扭.OK！
