[ubuntu-uk] Can I disable the power button?

[Stuart.Houghton at amnesty.org.uk]

My one-year-old son has a new favourite game - pressing the power button 
on his Dad's PC.

I am running Gnome  on Fiesty and whenever the power button is pressed it 
pops up a modal dialogue box asking if I want to restart, log out, switch 
off, etc.  I assume this happens via Gnome Power Manager.

What I would like is a way to disable this menu, so that hitting the power 
button either does nothing, or perhaps triggers a script that logs the 
number of times it has been pressed.  The GPM settings dialogue only gives 
me the option of 'Ask Me', 'Shutdown' or 'Hibernate'.

I have googled around the problem, but everything I have found seems to 
relate to laptops.  Does a desktop system use ACPI as well?

Cheers,
