Subject: Automatically saving and restoring an Emacs session in GNOME
Date: Tue, 2 Feb 2010 15:21:29 +0000

When I log out of my GNOME desktop, if Emacs (23.1) is running I get a
message that it is "not responding". I therefore usually manually quit
Emacs before logging out.

Looking at the source, it seems that Emacs does have xsession support,
so I am wondering what the problem is here. I am only running Emacs
interactively, not in any sort of daemon mode, so the only emacs
process I have running is the one I started myself.

I can't see anything about this in the manual, but of course the
trouble is that "session" occurs many times. I can't find "xsession"
at all in the manual, and "log out" doesn't yield anything helpful
either. Searching online suggests that Emacs may need some help with
GNOME, but I can't see which version or why exactly it needs help, if
it does.

Clarification sought!

Maybe your Emacs was built without libSM?  Did you compile it yourself?
In that case, check if HAVE_X_SM is defined in src/config.h.

If not, try to see if Emacs is linked to libSM.  On GNU/Linux that is
% ldd emacs

Please yes M-x report-emacs-bug when reporting bugs, it includes information 
that helps tracking down the bug.

It is the standard Ubuntu build of Emacs 23.1, and it is linked
against libSM. Is there any other information I can give?

Here's the output that report-emacs-bug gives:

Its value is
"1054f6786d2b365c6e126377503438154000000015820035"

> C-h v emacs-save-session-functions

Its value is nil

> C-h v emacs-session-filename

No such variable; there is a function of this name, however...

Yes sorry.  Anyway, you have session suport compiled in and Emacs talks to the 
session manager.

Do you have a directory ~/.emacs.d and is it writable?  If you start emacs, 
log out and then in again, do you have any session.* files in emacs.d?
Or any ~/.emacs.session.* files?

OK, the problem seems to be a bit more complex than I thought.

If I close down all my programs, log out, log in, start Emacs, then
log out and back in, everything works, and my session is restored.

If however I try to log out from a long-running session, GNOME says "A
program is still running: Emacs", and offers me the choice to log out
anyway, or to cancel the log-out action. If I ignore the warning and
log out anyway, then indeed the Emacs session is restored when I log
back in.

So in fact, my problem is really: why sometimes does Emacs refuse to
be killed? I tried for example starting an emacs client session, but
that didn't seem to trigger this problem.

In summary, it's a minor annoyance now that I understand what is going
on better, but it would be nice to work out why Emacs sometimes
refuses to die at first, althuogh it doesn't seem to matter if I just
log out anyway.

(I did come across another minor bug in the process which I'll now
file separately.)

This is usually Emacs not responding to the session manager, or taking too 
long time to do so.  I have an idea about this, I'll have to check it out.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

Are you still seeing this issue in recent Emacs/Gnome versions?  (I
can't recall seeing this myself in a long time.)
