This is "normal" behavior of g-p-m for a long time. It manages timeouts by
itself setting usuall Xorg DPMS to 0. I've reported a bug
http://bugzilla.gnome.org/show_bug.cgi?id=543956 some time ago, but this
is probably the best it can do. This has nothing to do with this
problem, unless Xorg changed its behavior and is kicking in DPMS at 0,
instead "never".
