[9fans] A note on using E

Just a note on using E with p9p. I forgot to start the plumber. That's
kind of important if you want to use E. :-)

Yup.  The script I use to start acme (in p9p) in my preferred
configuration (autoindent, 3 columns, specific fonts) uses my
'ensure_plumber' script:

#!/bin/sh
if 9p stat plumb > /dev/null 2>&1
then
        exit
else
        plumber
fi

to ensure that the plumber is running.  This works nicely for me, as I
can exit and restart acme, and the plumber continues running.  When I
log out of this linux system, however, t appears that the plumber is not
killed, and the next time I log in and start acme, the script sees that
the plumber is still running and doesn't start it.  Unfortunately, that
running plumber doesn't seem to be work right because when I click on a
URL in acme it doesn't get opened in my web browser.  I have to kill and
restart the plumber to get this to work.

I haven't been able to figure what is actually going wrong.  Any hints
or suggestions would be gratefully accepted.

	thanks,

The problem is that the old plumber does not have
access to your new X desktop, so it cannot start
a new firefox nor can it tell one running on the new
desktop to do anything.

The solution is to restart plumber always, perhaps in
your .xinitrc.

I have a few programs that need to be stopped when I log out, that aren't
stopped automatically (ssh-agent, plumber). I use KDE, so to do this, I
have a set of shutdown scripts that kill these processes on logout and
start them on login. Your window manager may have something similar for
you to use.

Ah, that makes sense.

Thanks for explanation Russ.
