KDE 4.10.5 and logging out

Hello,

I am using Slackware 14.1 with KDE 4.10.5 installed.

I there a way to set up the system so a file will execute upon logging out of KDE.
I do not mean after shutting down the system.

I would like to use the command "inotifywait" so when I log out of KDE this command will
set waiting for a command from a remote host to execute a script within.

Thanks.

Regards,

Jeff
