sudo apt-get update    #这一步是更新你的源列表，换源後必须执行
sudo apt-get dist-upgrade   #这一步是更新软件，如果你对新版本软件的需求不是那么迫切，可以不执行


4：设置中文界面
系统 -> 系统管理 -> 语言支持，在列表中的Chinese条目打勾。 同时将默认语言修改为Chinese（中国）并确定
根据提示进行下载安装

5：配置字体
sudo fontconfig-voodoo -f -s zh_CN

6：解决PDF电子文档的中文乱码
sudo apt-get install xpdf-chinese-simplified xpdf-chinese-traditional

7：安装JAVA环境支持
sudo apt-get install sun-java6-jre
sudo apt-get install sun-java6-jdk

8：安装多媒体解码器
sudo apt-get install audacious audacious-plugins audacious-plugins-extra libdvdcss2 libdvdnav4 libdvdplay0 libdvdread3 w32codecs libxine-extracodecs gstreamer0.10-pitfdll gstreamer0.10-ffmpeg gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-multiverse gstreamer0.10-plugins-ugly gstreamer0.10-plugins-ugly-multiverse

9：安装mplayer播放器
sudo apt-get install mplayer-fonts mplayer mplayer-skins mozilla-mplayer

11： 如何设置动态域名(可选)
#首先去 http://www.3322.org 申请一个动态域名
#然後修改 /etc/ppp/ip-up 增加拨号时更新域名指令
sudo gedit /etc/ppp/ip-up
#在最後增加如下行
w3m -no-cookie -dump 'http://username:password@members.3322.org/dyndns/update?system=dyndns&hostname=yourdns.3322.org'

将username:password按格式替换为你的用户名和密码 hostname替换为你的域名，其他不必更改。以上设置将在拨号时自动将动态域名解析挂载好。

12：安装BT下载软件
