最近安裝了ubuntu14.04,安裝時一般分三個區/,/swap和/home,具體/大小為10G-15G,/swap是內存大小的兩倍，
比如，我的內存是2G，那么/swap就是4G,剩下的給/home。
我的是用U盤安裝，用的工具是
簡單配置了一下：universial usb installer,很好用很強大很簡單。
1、 安裝搜狗輸入法，直接在官網上下在deb安裝包，下載完直接雙擊安裝就可以用了，這回ubuntu真無敵了。
2、安裝g++，用命令行安裝:sudo apt-get install g++
用命令g++ --version查看安裝版本
3、vim可以直接在軟件源里安裝或用命令sudo apt-get install vim
4、關於裝ubuntu14.04的時候遇到 sudo apt-get update出現 錯誤，說明源不可用了，那么就換一下源就可以了。
更換方法:
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup //備份源
sudo gedit /etc/apt/sources.list //打開刪除其中的內容，加入下面的內容

保存之后，用下面的命令使源生效:
sudo apt-get update
5、關於ubuntu14.04彈出"系統程序出現問題"的對話框，解決方法如下:
sudo gedit /etc/default/apport
把enable=1改為enable=0
最后，ubuntu用戶體驗越來越好了，給力十分。
