Hello Daryl,
some links only if you are interested in using mythwelcome in ubuntu.
https://help.ubuntu.com/community/MythTV/Install/WhatNext/ACPIWake
http://www.mythtv.org/wiki/Mythwelcome
Quickstart: You can activate it in /etc/mythtv/session-settings
There are comments in the file which explain that.
Have fun
Greetings
Stefan
