My one day for Ubuntu 11.04

It's two year ago that last time I really learn to use Linux. I installed Red flag Linux and Ubuntu 8.04. the former is similar to windows,and many people suggest to use Ubuntu or Fedora for learning. it take me one night to install keyboard input method, and the network is awful,so I give up.
Today,I install ubuntu again,and it has build-in keyboard input method. when I installed it,I chose Chinese simple.then I change the system language to English.there are two problem,one is some place still display english,another one is build-in keyboard input method is no started. I set many option to figure it out.

Then I find I don't like Unity theme, but I set System Setting->System->login screen setting->set default session,and restrat the computer,it didn't work. In forum,someone told it should be log out not restart.
at last I find Firefox can't display Chinese plain. try to chang many option,beyond my thinking,so many popular website use UTF-8 or at least GBK. www.sina.com.cn is still using GB-2312. at last,I didn't know how,I figure it out.
it's simple to install Qt Sdk in Ubuntu via Ubuntu software center. The nokia's Qt website Has a 1.7 GB SDK offline,it's horror,it contain many componets including Sybian Sdk.
Via Ubuntu Software Center,I just download 128mb files to install the Qt SDK. it's wondeful.
This time I install Ubuntu is smooth. because I has read many document about. the former times ...

Here I just experience my english. and the blog is just for me.
