Botond, Greg,

Thank you for replying.

I tried this, and whenever I pressed the special keys, instead of their 
output being trapped in xev, it would actually do the action. i.e. 
pressing the "Sleep" button put the computer to sleep, and even upon 
waking it up again, there was no recorded response in the xev output.

I do have acpid running as a daemon. And looking in /etc/acpi, there's a 
whole bunch of shell scripts.

dave@example.com:~$ cd /etc/acpi
dave@example.com:/etc/acpi$ ls
ac.d lid.sh power.sh stopbtn.sh...

There's one in there called "sleep.sh", which I assume is the one being 
called (?).

Looking at it, it was above my ability to make any corrections, and I'm 
not 100% sure this is the responsible script.

At this point I realized that maybe having additional functions like 
putting the hard drives to sleep and whatnot are a good thing.

So I've rephrased my objectives, and posted them to the Ubuntu mailing 
list. That message reads as below:

Ubuntu Users,

On my keyboard, I have two keys marked "Sleep" and "Wake Up".

They work fine, except that I want to make one modification. When 
"Sleep" mode is initiated, the screen saver gets locked so that I have 
to enter a password when the system is activated again.

That's a good security default I suppose, but I also use my computer as 
a MythTV entertainment system, and the password entry screen prevents me 
from easily waking the system up from remote.

What I would like to be able to do is the following 3 things:

1. Alter the "Sleep" button so that it does not lock the system with any 
password settings.

2. Map one of the buttons on my remote control to do the exact same 
action as the "Sleep" button on the keyboard.

3. Map one of the buttons on my remote control to do the exact same 
action as the "Wake Up" button on the keyboard.

What I've done so far:

My remote works, and I have two buttons mapped to do the following:
xset dpms force off
xset dpms force on

However, if I hit "Sleep" on the keyboard, the remote button won't wake 
the system up. I'm not sure if the system has a way of shutting down the 
daemon that is responsible for listening for the remote control. Also, 
there is the aforementioned password problem.

I had a little help from my local Linux User's Group, and also looking 
on the web, so I think the process responsible for the keyboard keys is 
"acpi", and that it's settings are in /etc/acpi

However, what I found there were a multitude of shell scripts that are 
on a level much above me. And this is where I got stuck.

I can't quite determine how to track where and how commands from these 
special keys are initiated, and also I can't determine how to modify 
them so as to lose the password security option.

Any advice would be much appreciated. Thank you.
