曾经心血来潮写过一个Ubuntu的配置教程，还美其名曰《邂逅Ubuntu》系列，后来Ubuntu更新了，GNOME也变成了gnome shell，但是教程再也没更新过（惭愧不已）。适逢Ubuntu 12.04刚更新不久，简单记录下配置的流程。
本文主要记录了安装Ubuntu 12.04 (Precise) 之后的配置美化过程，主要包含：
1、配置软件源；2、安装配置gnome shell取代unity；3、安装相关软件；4、配置杂项。

配置软件源
我的策略是教育网一组，公网一组，官网一组，其次主要考虑地理位置和具体连接的速度。
教育网推荐是使用清华、北交、上交的（其一即可），公网推荐sohu（中国官方源）、163的（同样选择其一）。

配置好之后记得更新升级
sudo apt-get update
sudo apt-get upgrade
# 安装配置gnome shell
之前折腾过Arch、Gentoo、Mint、Deepin都是因为Ubuntu换了unity，也算因祸得福，学到了很多东西，现在可以兼容了，当然果断上之。
安装基本桌面
sudo apt-get install gnome-shell # gnome shell 桌面
sudo apt-get install gnome-tweak-tool # 高级配置工具
# 安装图标和GTK主题
sudo add-apt-repository ppa:tiheum/equinox # 添加图标主题PPA
sudo add-apt-repository ppa:satyajit-happy/themes # 添加GTK主题PPA
sudo apt-get update # 更新软件源
sudo apt-get install faenza-icon-theme faience-icon-theme # 两款Icon theme
sudo apt-get install evolve-gtk-theme orion-gtk-theme # 两款 GTK theme
我选择的Icon theme是Faience，Window theme和GTK+ theme都是Evolve
# 安装gnome shell extension
可以通过PPA和网站两种方式安装，主要还是个人喜好和需要，通过gnome-tweak-tool进行设置即可，这里只列出作者使用的部分
通过PPA安装
