在安裝中文語言包和中文輸入法之前，我先配置好了pc-arm的交叉編譯環境和QT，因為我要在qt中使用中文，所以不知道是否應該先把開發環境配置好再安裝輸入法。

1.更新源列表：

ubuntu上的軟體安裝都需要實時聯網，所以在安裝軟體時都應該保持網路暢通。安裝軟體需要獲取網路資源，這些資源的地址都存在/etc/apt/souces.list這個列表檔案裡，網路上的源有很多，下面我列出一些。

官方源：

然後就要更新源列表了。

#sudo apt-get update

2.安裝中文語言包：

點選右上角齒輪狀的按鈕，或者開啟Dash home搜尋，找到System Settings->Language Support，然後它會自動檢查更新（等它更新完，我剛開始就直接把它關掉了，結果中文輸入法怎麼都裝不上），更新完以後，點選Install/Remove Languages...，選上Chinese(Simplified)，點選Aplly，然後它就會自動下載安裝了（如果下載卡住了，沒速度了，關了重新開啟接著下）。

安裝完了之後發現“漢語（中國）”還是黑的呢！別急，只需要按住滑鼠把它拖到最上邊就可以了，OK，Close，ReStart（重啟系統）！

3.刪除所有輸入法：

我是怕輸入法太多而引起衝突，而且我也不喜歡有幾個輸入法，看著煩，就增加了這步。

我是手動找到/etc/X11/xinit/xinput.d這個資料夾，刪除前先備份（養成好習慣），刪除除all_ALL，none以外的所有檔案。

4.安裝ibus輸入法框架及漢語拼音：

開啟終端，安裝ibus，拼音，五筆

# sudo apt-get install ibus ibus-clutter ibus-gtk ibus-gtk3 ibus-qt4
# sudo apt-get install ibus-pinyin
# sudo apt-get install ibus-table-wubi

ibus-setup

Input Method選項卡中，選中Customize active input methods，Select an input method->Pinyin，Add。

至此中文輸入法就裝完了。
