ubuntu 14.04 删除ibus输入法引发的问题及解决方法

      删除自带的ibus输入法，导致系统设置及其他一些东西没法使用。

解决方法：

sudo apt-get install ubuntu-desktop

sudo reboot

安装之前可能需要更换一个速度快的软件源，本来可以在系统设置里设置，但是现在系统设置打不开了，所以只能在终端里配置了。

cd /etc/apt/

sudo cp sources.list sources.list.bak

sudo gedit sources.list

清空内容，加入如下内容：

deb http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse

deb http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse

deb http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse

deb http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse

然后更新软件列表：

sudo apt-get update
