Who can give a document about font install and set?

零二年的夏天

These days reads some documents from CU and Linuxfans.
And then I try to modify the file of my computer.But now as you see I lost my Chinese input.
I use fcitx,if I type the command fcitx in terminal it says:

1. 
   
2. fcitx
   
3. 无法加载字体 -*-fixed-medium-r-normal--16-*-*-*-*-*-*-*,-*-*-medium-r-normal--16-*-*-*-*-*-zh_CN.GBK-*
   
4. 字体区域 zh_CN.GBK 不支持! 使用 zh_CN.GB2312
   
5. 
   
6. fcitx:Abnormal exit
   
7. Signal No.: 11
   

复制代码

So now anybody can give a document about the font?
