I upgraded my mythbuntu 7.10 box by apt-get dist-upgrades on the
weekend to 8.04.  Everything went quite nicely, except I too had a
problem whereby the FEs would randomly decide that they want to blank
screen and they wouldn't come back to life.  Nothing from a keyboard,
SSH, or the remote.  (I too have Intel chipsets, these machines being
Aopen MP915-P and MP915-X machines).

I have done plenty of head scratching and last night just decided to
do a clean install of mythbuntu 8.04 on one of them.  So far, so good.
 I managed to leave it on the menu overnight and this morning when I
turned the TV on, the screen was blank.  Pressed the remote button and
the screen came alive and I was back at the menu.  I have left the FE
switched on today and will probably leave it another full day, but if
all goes well, I will just clean install all my other FEs too!

This screen blanking seems to be a common problem on this list and on
the mythbuntu forums, but one that has no clear fix.  I hate not
knowing why something is broken (since I am never know if it is
actually fixed) but I have had such a crap weekend because of this
upgrade that if this re-install fixes it, I am happy :P

Best of luck,
Whytey
