My installation was based on mythbuntu however I have stripped out most 
of what made that a plug and play install. It did indeed have a screen 
saver (simple fade to black) which I have since disabled. There is still 
an issue with what I assume is dpms related in that my screen goes black 
after a while and then ~ an hour later comes back on. Interesting thing 
is that it requires 2 button pushes to activate the first command after 
this happens. Not sure if this has anything to do with the freezing 
issue however it does continue to freeze with the screen saver disabled.

Hope this helps.
