刚安装好的不支持中文输入（我用的是免费赠送版本的ubuntu7.10）

解决方法如下：

很多文章说的要换源，我想如果你的网络状况很好的话，最好是不换了，终端里输入

sudo gedit /etc/sources.list

将下面的代码替换之：

#CN99 deb http://ubuntu.cn99.com/ubuntu gutsy main restricted universe multiverse

deb-src http://ubuntu.cn99.com/ubuntu gutsy main restricted universe multiverse

deb http://ubuntu.cn99.com/ubuntu gutsy-backports main restricted universe multiverse

deb-src http://ubuntu.cn99.com/ubuntu gutsy-backports main restricted universe multiverse

deb http://ubuntu.cn99.com/ubuntu gutsy-proposed main restricted universe multiverse

deb-src http://ubuntu.cn99.com/ubuntu gutsy-proposed main restricted universe multiverse

deb http://ubuntu.cn99.com/ubuntu gutsy-security main restricted universe multiverse

deb-src http://ubuntu.cn99.com/ubuntu gutsy-security main restricted universe multiverse

deb http://ubuntu.cn99.com/ubuntu gutsy-updates main restricted universe multiverse

deb-src http://ubuntu.cn99.com/ubuntu gutsy-updates main restricted universe multiverse

#上海交大

deb http://ftp.sjtu.edu.cn/ubuntu/ feisty main multiverse restricted universe

deb http://ftp.sjtu.edu.cn/ubuntu/ feisty-backports main multiverse restricted universe

deb http://ftp.sjtu.edu.cn/ubuntu/ feisty-proposed main multiverse restricted universe

deb http://ftp.sjtu.edu.cn/ubuntu/ feisty-security main multiverse restricted universe

deb http://ftp.sjtu.edu.cn/ubuntu/ feisty-updates main multiverse restricted universe

deb http://ftp.sjtu.edu.cn/ubuntu-cn/ feisty main multiverse restricted universe

deb-src http://ftp.sjtu.edu.cn/ubuntu/ feisty main multiverse restricted universe

deb-src http://ftp.sjtu.edu.cn/ubuntu/ feisty-backports main multiverse restricted universe

deb-src http://ftp.sjtu.edu.cn/ubuntu/ feisty-proposed main multiverse restricted universe

deb-src http://ftp.sjtu.edu.cn/ubuntu/ feisty-security main multiverse restricted universe

deb-src http://ftp.sjtu.edu.cn/ubuntu/ feisty-updates main multiverse restricted universe

#cn99的设置

deb http://archive.ubuntu.com/ubuntu/ gutsy multiverse

deb http://ubuntu.cn99.com/ubuntu-cn/ feisty main restricted universe multiverse

当然，你有更好的话，就换成你的了。

然后就是检查更新了，方法：

sudo apt-get update

最后打开 System--系统管理--Language Support。选中Chinese，点击应用Ubuntu会自动安装中文输入法。
