每次重装系统的时候都是要到google上搜索一堆的东西，很不方便，而且我的记性很不好容易忘。准备逐步的完善这篇文档，给自己以后再配置系统的时候能够方便一些。
（1） 重装系统后，我做的第一件事情就去更新一下sourcelist，在这里贴出我的源列表：

将原来的sources.list备份后那么就开始sudo aptitude update吧！
(2) 修改.vimrc文件，配置我的VIM
由于我主要是应用vim来写代码，下载一些vim专用的插件将vim配置成IDE这种图形界面的东西，将会十分的方便。主要是参考了网络上http://blog.csdn.net/wooin/archive/2007/10/31/1858917.aspx
这篇文章，在这里贴出来我的.vimrc配置：

（3）解决ubuntu系统网页显示字体
备份49-sansserif.conf这个字体配置文件
$ sudo cp /etc/fonts/conf.d/49-sansserif.conf /etc/fonts/conf.d/49-sansserif.conf.bak
删除49-sansser做完后重启firefox就可以了。 if.conf文件
$ sudo rm /etc/fonts/conf.d/49-sansserif.conf
(4) 解决Ubuntu8.04版本下PDF文件显示乱码问题
安装poppler-data
方法一 从8.04开始，源中有poppler-data安装包
sudo apt-get install poppler-data
方法二 源中没有的话，下载编译好的deb安装包
sudo dpkg -i poppler-data_0.2.0-1_i386.deb
方法三 去官方下载tar.gz压缩包
wget -c poppler-data-0.1.1.tar.gz
解压
sudo tar xzvf poppler-data-0.1.1.tar.gz -C /usr/local/ && cd /usr/local/poppler*
sudo make install datadir=/usr/share
