I didn't mean start emacs via emacsclient, I meant *in this
condition* which emacs server has started in Xorg.

But there has been. See two screenshots, first is org-mode in emacs
server, which is running in the dtach sesstion on urxvt; second is
org-mode in emacsclient which is with the same emacs server:
            http://paste.ubuntu.org.cn/i8055
            http://paste.ubuntu.org.cn/i8054
You can see, in emacsclient, the column view can't display properly,
it's not relative to the color-theme. Emacs server works well.

I think my words have misled you, sorry.

I start emacs server in console(differ it with x terminal), and use
emacsclient on xorg. But you see, emacsclient has something wrong with
org-mode's column view. So I want to use emacs server instead of
emacsclient. 

(hmm, maybe I got why you can't understand me, what I mean emacs server,
is that the server frame, emacsclient is the client frame.)

Now what I want is: Start emacs server on xorg, then run an emacsclient
in console and make it to be a server, so the old client becomes new
server and the old server becomes client?
