保存下面的代码到文件sublime_imfix.c(位于~目录)

#include 
void gtk_im_context_set_client_window (GtkIMContext *context,GdkWindow    *window)
{
          GtkIMContextClass *klass;
          g_return_if_fail (GTK_IS_IM_CONTEXT (context));
          klass = GTK_IM_CONTEXT_GET_CLASS (context);
          if (klass->set_client_window)
                              klass->set_client_window (context,window);
          g_object_set_data(G_OBJECT(context),"window",window);
          if(!GDK_IS_WINDOW (window))
                              return;
          int width = gdk_window_get_width(window);
          int height = gdk_window_get_height(window);
          if(width != 0 && height !=0)
                              gtk_im_context_focus_in(context);
}

将上一步的文件进行编译

cd ~
gcc -shared -o libsublime-imfix.so sublime_imfix.c  `pkg-config --libs --cflags gtk+-2.0` -fPIC

如果如果“NO package 'gek+-2.0' found”，解决办法就是下面这个命令，安装这个包：

sudo apt-get install libgtk2.0-dev

将上一步产生的.so文件移动到/opt/sublime_text/目录下

sudo mv libsublime-imfix.so /opt/sublime_text/

修改/usr/bin/subl文件内容

sudo gedit /usr/bin/subl
将
#!/bin/sh
exec /opt/sublime_text/sublime_text "$@"
修改为
#!/bin/sh
LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text "$@"

为了使得在用鼠标右键打开文件的时候可以使用中文，可以修改文件sublime_text.desktop。如果没有这个文件，就不用修改了

sudo gedit /usr/share/applications/sublime_text.desktop
将[Desktop Entry]中的字符串
Exec=/opt/sublime_text/sublime_text %F
修改为
Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text %F"
将[Desktop Action Window]中的字符串
Exec=/opt/sublime_text/sublime_text -n
修改为
Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text -n"
将[Desktop Action Document]中的字符串
Exec=/opt/sublime_text/sublime_text --command new_file
修改为
Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text --command new_file"
