i would advise you to look into your acpi scripts directory, probably 
/etc/acpi/

in my power.sh, I can for example find :

        getXuser;
        if [ x"$XAUTHORITY" != x"" ]; then
            export DISPLAY=":$displaynum"
            su $user -c "xscreensaver-command -throttle" &
            xset dpms 0 0 120


so that is more likely to interact with dpms through such a script.

By the way, does it happen to you to plug / unplug your laptop and not 
use it right after ?
Because I do that when I come back home, and when I carry it, it is 
supended ... and if I plug it, I do not wake it up if I do not want to 
use it ...
Similary, if I unplug it, i will probably want to suspend it right 
after, if not already done ... so the screen would wake up as well :)
