ubuntu 14.04安装

     最近安装了ubuntu14.04,安装时一般分三个区/,/swap和/home,具体/大小为10G-15G,/swap是内存大小的两倍，

比如，我的内存是2G，那么/swap就是4G,剩下的给/home。

     我的是用U盘安装，用的工具是

     简单配置了一下：universial usb installer,很好用很强大很简单。

    1、 安装搜狗输入法，直接在官网上下在deb安装包，下载完直接双击安装就可以用了，这回ubuntu真无敌了。

    2、安装g++，用命令行安装:sudo apt-get install g++

        用命令g++  --version查看安装版本

    3、vim可以直接在软件源里安装或用命令sudo apt-get install vim

    4、关于装ubuntu14.04的时候遇到 sudo apt-get update出现  错误，说明源不可用了，那么就换一下源就可以了。

        更换方法:

            sudo cp /etc/apt/sources.list  /etc/apt/sources.list.backup  //备份源

            sudo gedit /etc/apt/sources.list    //打开删除其中的内容，加入下面的内容

            #163源

        deb-src http://mirrors.oschina.net/ubuntu/ trusty-security main restricted universe multiverse
        deb-src http://mirrors.oschina.net/ubuntu/ trusty-updates main restricted universe multiverse

       保存之后，用下面的命令使源生效:

        sudo apt-get update

    5、关于ubuntu14.04弹出"系统程序出现问题"的对话框，解决方法如下:

          sudo gedit /etc/default/apport

          把enable=1改为enable=0

      

         最后，ubuntu用户体验越来越好了，给力十分。
