I don't know if this is any help, but DPMS (display power management 
signalling) may be the problem. On FC5, commenting out the line "Options  
"DPMS" in the monitor section of /etc/X11/xorg.conf, resolved the problem, 
and now the monitor stays on all the time.

Commenting out that line in FC6 did not work, and  neither in Debian Lenny 
after some X updates. I use KDE, and have put a simple script in 
~/.kde/autostart on Debian Lenny. This runs xset -dpms, which disables DPMS 
when you login, see below.

#!/bin/bash

xset -dpms

The above script works ok on Debian Lenny if you're using KDE. Make sure to 
make the script executable (chmod +x), or just click the exec box in the 
file's properties/permissions. I havn't tried the script on FC6 yet, but it 
should work ok. Same perhaps for F7.

If you're using Gnome I don't know, but perhaps there is some similar 
autostart directory in Gnome where you can run the script from.


2¢ worth of perhaps totally useless info, but works for me nevertheless.
