I'd guess it's most likely DPMS that's causing the problem.
There are options you can put in your XConfig file, but my
experience is they were not effective for the cases I tried

For runlevel 3, text login, I have had success doing "startx
-- -dpms" rather than just "startx". The double hyphen
makes everything after it (the "-dpms") a server option
rather than a client option. I don't know how to turn off
DPMS for runlevel 5, graphical login.

Good luck.
