发现Sublime Text不支持中文，我用的是Fctix，查了好长时间教程搞定了，在此分享并记录下，最后附上本次所需文件的下载地址。
1、 复制如下的代码为sublime_imfix.c文件并放到sublime_text的安装目录下， 默认为/opt/sublime_text。
/*
sublime_imfix.c
Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.

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 <gtk/gtk.h>
#include <gdk/gdkx.h>
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;
GdkRectangle rect;
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.
static GdkFilterReturn event_filter (GdkXEvent *xevent, GdkEvent *event, gpointer im_context)
{
XEvent *xev = (XEvent *)xevent;
if(xev->type == KeyRelease && GTK_IS_IM_CONTEXT(im_context)) {
GdkWindow * win = g_object_get_data(G_OBJECT(im_context),"window");
if(GDK_IS_WINDOW(win))
gtk_im_context_set_client_window(im_context, win);
}
return GDK_FILTER_CONTINUE;
}
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);
if(!GDK_IS_WINDOW (window))
return;
g_object_set_data(G_OBJECT(context),"window",window);
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);
local_context = context;
}
gdk_window_add_filter (window, event_filter, context);
}
2、 安装编译所需的工具，如果已经安装则跳过
sudo apt-get install build-essential
sudo apt-get install libgtk2.0-dev
3、 安装完成后，进入sublime_text的安装目录，在命令行下编译，生成-o 之后的文件，记住它的位置：
gcc -shared -o libsublime-imfix.so sublime_imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC1
4、 命令行中进入/usr/share/applications目录下，用subl打开sublime_text.desktop文件，即sublime_text的类似于快捷方式的文件，可能名字会有不一样，可先用ls查看一下文件名字,
sudo subl sublime_text.desktop
然后将三个对应Exec更改为如下所示：
Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text %F"
Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text -n"
Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text --command new_file"
注意这里一定要是双引号，因为用单引号会出现只弹出Sublime_text，不打开文件等情况。网上好多教程在这一步都是单引号，可能是版本已经不适用,保存文件，现在用subl打开文本已经支持中文。
将Sublime Text设置为默认文本编辑器
1. 命令行输入以下命令：
sudo subl /etc/gnome/defaults.list
在里面ctrl+h替换所有gedit。desktop为sublime_text.desktop保存即可。
至此，Sublime Text已经是Ubuntu默认的文本编辑器了。
