It's very likely DPMS [1] interfering with Gnome Screensaver. You can
try to set other DPMS timings (or turn DPMS off) using the xset command,
and write them into xorg.conf if this indeed turns out to be the
problem. Here [2] are good in-depth instructions for testing and solving
it.

Here [3] is a straightforward article about the issue in Feisty, with
instructions.

The forums have several articles about it, too, but they are down at the
moment. Here's Google's cache for one of them [4]
