emacs and emacsclient on different displays

emacs and emacsclient on different displays

[Jim Barbour]

Hey Folks,

Should I be able to run emacs and emacsclient on different displays?

i.e. start emacs on my linux machine in my office, set a server name
and start an emacs server.  Do work.  Then, come home, ssh into the
office, and run emacsclient and use the same buffers I was using at
work.   I'd like all of this to be in X windows, not in a TTY.

i.e.

host1 % echo DISPLAY
localhost:0.0
host1 % emacs...
eval: (setq server-name "test1")
eval: (start-server)
...

<later>

host1 % echo $DISPLAY
localhost:14.0
host1 % emacsclient -s test1 -c foo
Waiting for Emacs...X11 connection rejected because of wrong authentication.
*ERROR*: Connection lost to X server `localhost:14.0'

However, if I run xterm at that same prompt, it comes up just fine.

Can anyone let me know if what I want to do here is possible, and what
I might be doing wrong?

Thanks Very Much,

Jim

Yes.

Does "xterm" bring up an xterm?  Could it be that your original "emacs"
was started with a different .Xautority file, maybe?
I.e. compare $XAUTHORITY in each cases (ideally it should be
empty/undefined in each case).

Look at this message, 
http://lists.gnu.org/archive/html/help-gnu-emacs/2009-09/threads.html. 
The rest of the thread is also very instructive about how emacsclient 
and tramp works.

Hi Jim,

I think my previous reply didn't go through, if this is a double post,
I apologise.

Hey Suvaya,

Could you be more specific which thread you're referring to?

The page you provided has a whole lot of them :)

Thanks,

Jim

I am extremely sorry Jim, its way too early in the morning for me and 
copied the wrong URL. :-p

The post I was referring to is this one,
http://lists.gnu.org/archive/html/help-gnu-emacs/2009-09/msg00100.html

Its part of the thread titled "Using tramp to connect to a remote emacs 
session". Sorry about the mix-up. Shouldn't be posting so early in the 
morning.
