Hey All,

I think someone here will be able to point me with a solution to this
problem.

A few months ago I wrote this tutorial
http://ubuntuforums.org/showthread.php?t=1076486 which basically catches lid
and dock events so that you can then do whatever you want. I did this
getting bits and pieces of information all over the place, including this
mailer from which I got how to catch the dock/undock event. This was done on
Ubuntu 8.10.

Now that I try the exact same procedure on Ubuntu 9.04 I get a problem with
the udev rule file.

Basically what I do is create a file /etc/udev/rules.d/80-thinkpad-T61.rules
with

KERNEL=="dock.0", ATTR{docked}=="1", RUN+="/etc/thinkpad/dock.sh 1"
KERNEL=="dock.0", ATTR{docked}=="0", RUN+="/etc/thinkpad/dock.sh 0"

And then create a /etc/thinkpad/dock.sh file with

#!/bin/sh
# wait for the dock state to change
sleep 1
DOCKED=$(cat /sys/devices/platform/dock.0/docked)
case "$DOCKED" in
    "0")
    #undocked event - do whatever you want here
    ;;
    "1")
    #docked event - do whatever you want here
    ;;
esac
exit 0

It work fine, it catches the event and does what I want to do. BUT, for some
reason during startup it's creating a huge delay, like 3 minutes. As soon as
I move the file /etc/udev/rules.d/80-thinkpad-T61.rules out of that folder
startup times go back to normal.

Any ideas or pointers?

Thanks!
