Name
  XActivateScreenSaver - activate screen blanking.

Synopsis
  XActivateScreenSaver(display)
	Display *display;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

Description
  XActivateScreenSaver()  turns  on  the screen saver using the parameters set with XSetScreenSaver().	The screen saver blanks the screen or
  makes random changes to the display in order to save the phosphors from burnout when the screen is left unattended for an  extended  period
  of  time.   The interval that the server will wait before starting screen save activity can be set with XSetScreenSaver().  Exactly how the
  screen saver works is server-dependent.
