ubuntut13.10下面解决sublime text2里不能输入中文的问题
T61上装了Ubuntu 13.10 64bit，再按照自己的习惯安装了cario-dock和sublimetext2，由于ibus在这个版本下面工作不正常，最后安装了fcitx作为自己的输入法。
先说一个大家经常碰到的问题，fcitx用ctrl+space不能切换输入法的解决方法 。
在‘ 应用菜单’里的‘system setting’里的‘区域和语言’里的'切换到上个源'，默认选上了‘ctrl+space’，和fcitx的冲突，选中后按'backspace'取消掉
2、要通过ppa方式安装sublime text2，以前的下载包、解压什么的太老土了。
sudo add-apt-repository ppa:webupd8team/sublime-text-2 sudo apt-get update sudo apt-get install sublime-text
3、然后把下面代码的代码保存下来，放到你的/home/leo/Share下面,(leo是我的用户名，放哪里不是很重要，后面路径参数要写对)，命名为sublime-imfix.c（感谢ubuntu.org.cn acmego）

4、终端下，安装编译时候需要的环境：
sudo apt-get install build-essential sudo apt-get install libgtk2.0-dev
5、终端下，进入sublime-imfix.c所在目录后，开始编译，后会得到libsublime-imfix.so
gcc -shared -o libsublime-imfix.so sublime_imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
7、然后修改ST2的启动配置
sudo gedit /usr/share/applications/sublime-text-2.desktop
8、找到
Exec=/usr/bin/subl %F
修改成，注意括号的位置，要把%F给包括进来
Exec=bash -c 'LD_PRELOAD=/home/leo/Share/libsublime-imfix.so /usr/bin/subl %F'
同时把
Exec=/usr/bin/subl -n Exec=/usr/bin/subl --command new_file
改成
Exec=bash -c 'LD_PRELOAD=/home/leo/Share/libsublime-imfix.so /usr/bin/subl' -n Exec=bash -c 'LD_PRELOAD=/home/leo/Share/libsublime-imfix.so /usr/bin/subl' --command new_file
9、这里，通过应用程序能直接打开sublimetext2，并用能输入中文 ，但是把sublime-text固定到cario-dock的启动栏里还不能正常启动，因此要作一些配置。
在该启动器的配置项里，把'comand to launch on click:'改成‘LD_PRELOAD=/home/leo/Share/libsublime-imfix.so /usr/bin/subl’，这样可以在dock里直接点sublimetext2按钮启动并输入中文。
