 From the shell, run
gnome-screensaver-preferences

or from  the menu  system -> preferences -> Screensaver

There you can enable or disable the screen saver, and you can also do other
settings like what should happen if you close the lid, and various
other power settings.

As far as makeing the screen saver wake up without user intervention,
I don't know ....    If your keyboard can send back some key code upon
receipt of some escape sequence, then it might be possible to wake up
the screen saver. Ditto with the mouse.

I wonder if output to the screen could alert the screen saver to expose
the screen again???
