This is the functionality you want:
> man xscreensaver-command
-deactivate
This tells xscreensaver to pretend that there has just been
user activity. This means that if the screensaver is active
(the screen is blanked), then this command will cause the
screen to un-blank as if there had been keyboard or mouse
activity. If the screen is locked, then the password dialog
will pop up first, as usual. If the screen is not blanked,
then this simulated user activity will re-start the countdown
(so, issuing the -deactivate command periodically is one way to
prevent the screen from blanking.)

Title:
Inhibition of xscreensaver with XScreenSaverSuspend fail
Status in xscreensaver package in Ubuntu:
Invalid
Bug description:
Binary package hint: xscreensaver
I'm trying to stop xscreensaver using XScreenSaverSuspend, but it doesn't
seems to work.
I writed a test case to test the behavior, and it confirmed the problem. (see
tect.c attached)
XScreenSaverSuspend is used at least in mplayer and gnome-mplayer to stop the
screensaver when a video is played.
