As crazy as it sounds, I think there may be a connection between the
networking stuff and the problems with the screen going blank. At least, on
FC7, it appears so.
This past summer, I was forced to rebuild my older machine to overcome the
zap2It problem. I built an FC7 box, and everything worked mostly correct,
except for my screen going blank after some minutes of inactivity. this
never happened while I was watching a show, but if I walked away while
sitting at one of the menus, it would go blank. I tried all the xorg
settings that people have suggested, but nothing worked. because I was able
to recover the machine with the remote, I never pursued this any further. I
also thought it might not be so bad for my plasma display if the screen went
blank after long periods of inactivity.
Fast forward to a week ago....
Since my next project is to build a new frontend machine, I needed to make
my existing backend have a static IP address. At least, I think this is
necessary in order for the frontend to locate the backend consistently on
the same IP address. Anyway, I made changes to my backend to switch from
DHCP to a static IP address. This worked fine, but then my screen started
going blank, even if I was in the midst of watching a show. Even worse, it
was not possible to recover with just the remote. I had to go jiggle the
mouse, or tap the keyboard, to recover from the blank screen. Very
annoying. The WAF went down the tubes very quickly.
So, after reading this thread, I was able to fix the problem by following
>>Or put the commands in either /etc/X11/xinit/Xsession or /etc/X11/

Again, no amount of fiddling with xorg.conf seems to do any good.
It sure looks like the original poster stumbled upon something similar to
what I saw, based on his comment
>>the only thing that I recall changing is installing a dhcp server and tftp
server (which uses xinetd) for use with my MediaMVP.
