How do I run a bash script at the start of the KDE logout process?

The reason I'm asking is that the KDE logout process on my laptop is very
slow, taking about 25 seconds before it gets as far as terminating the
X-server. I've suspected various KDE services of causing the problem,
and I've noticed that stopping one or the other seemed to speed things
up, but I've now realised that services that can use the sound system
seem to be to blame. I've found that a sure way of chopping 20 seconds
from the logout time is to kill kmix, which displays the taskbar volume
control, before logging out. I'd guess it's something to do with the
driver for Intel 82801DBM sound chip.

Unfortunately, if I put "pkill kmix" in a script in the "~.kde/logout"
directory, it doesn't run until *after* this annoying delay.

So is there a way to run a script at (or soon after) the *start* of the
KDE shutdown process, rather than after it has completed?

Try putting the following three lines in a file, chmod a+x, the file, create an icon
on the desktop that runs the script, and click on the icon to logout ...
#!/bin/bash
dcop kmix MainApplication-Interface quit
dcop kdesktop default logout

Brilliant. Thanks. Got no answer when I asked this at www.kde-forum.org

I put the big red switchoff button icon (from system icons, actions) onto
the applet and dragged it into the task bar, just to the right of the
start menu icon, where I shouldn't forget to use it.

The apps that need to be closed to ensure a shutdown that doesn't jam for
20 seconds seems to vary with the phase of the moon or something. I'm
now shutting down kmix, klaptop and knemo, so the complete script is now:

#! /bin/bash
dcop kded kded unloadModule "knemod"
dcop kded kded unloadModule "klaptopdaemon"
dcop kmix MainApplication-Interface quit
dcop kdesktop default logout
