本着发现问题，解决问题的原则，咱就找解决方法呗，经过Google和论坛发帖，找到了解决方法。
编译共享内库
1. 保存下述代码为 sublime-imfix.c 文件
引用:/*
sublime-imfix.c
Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.
By Cjacker Huang
gcc -shared -o libsublime-imfix.so sublime_imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
LD_PRELOAD=./libsublime-imfix.so sublime_text
*/

#include
typedef GdkSegment GdkRegionBox;
struct _GdkRegion
{
long size;
long numRects;
GdkRegionBox *rects;
GdkRegionBox extents;
};
GtkIMContext *local_context;
void
gdk_region_get_clipbox (const GdkRegion *region,
GdkRectangle *rectangle)
{
g_return_if_fail (region != NULL);
g_return_if_fail (rectangle != NULL);
rectangle->x = region->extents.x1;
rectangle->y = region->extents.y1;
rectangle->width = region->extents.x2 - region->extents.x1;
rectangle->height = region->extents.y2 - region->extents.y1;

rect.x = rectangle->x;
rect.y = rectangle->y;
rect.width = 0;
rect.height = rectangle->height;
//The caret width is 2;
//Maybe sometimes we will make a mistake, but for most of the time, it should be the caret.
if(rectangle->width == 2 && GTK_IS_IM_CONTEXT(local_context)) {
gtk_im_context_set_cursor_location(local_context, rectangle);
}
}
//this is needed, for example, if you input something in file dialog and return back the edit area
//context will lost, so here we set it again.

{

if(width != 0 && height !=0) {
gtk_im_context_focus_in(context);
local_context = context;
}
gdk_window_add_filter (window, event_filter, context);
}
2. 安装C/C++的编译环境和gtk libgtk2.0-dev
sudo apt-get install build-essential
sudo apt-get install libgtk2.0-dev
3. 编译共享内库
gcc -shared -o libsublime-imfix.so sublime_imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
4. 启动 Sublime Text 2
好了，现在执行下述命令启动 Sublime Text 2，就可以使用fcitx输入中文了！
LD_PRELOAD=./libsublime-imfix.so sublime_text
但是这样的话，我们每次都要在终端里面使用命令启动sublime text 2，这样很不方便，接下来我们还要通过修改sublime-text-2.desktop达到点击图标启动。
打开终端进入applications修改sublime-text-2.desktop
cd /usr/share/applications
sudo vim sublime-text-2.desktop
打开sublime-text-2.desktop后，将
Exec=/usr/bin/sublime-text-2 %F
修改为
Exec=bash -c 'LD_PRELOAD=/usr/lib/libsublime-imfix.so /usr/bin/sublime-text-2' %F
还有将
Exec=/usr/bin/sublime-text-2 --new-window
修改为
Exec=bash -c 'LD_PRELOAD=/usr/lib/libsublime-imfix.so /usr/bin/sublime-text-2' --new-window
好了，接下来你在dash中点击打开sublime text2吧，开始你的代码之旅吧。
