  32 /*  First, some background: there are three distinct server extensions which
  33  *  are useful to a screen saver program: they are XIDLE, MIT-SCREEN-SAVER,
  34  *  and SCREEN_SAVER.
  35  *
  36  *  The XIDLE extension resides in .../contrib/extensions/xidle/ on the X11R5
  37  *  contrib tape.  This extension lets the client get accurate idle-time
  38  *  information from the X server in a potentially more reliable way than by
  39  *  simply watching for keyboard and mouse activity.  However, the XIDLE
  40  *  extension has apparently not been ported to X11R6.
  41  *
  42  *  The SCREEN_SAVER extension is found (as far as I know) only in the SGI
  43  *  X server, and it exists in all releases since (at least) Irix 5.  The
  44  *  relevant header file is /usr/include/X11/extensions/XScreenSaver.h.
  45  *
  46  *  The similarly-named MIT-SCREEN-SAVER extension came into existence long
  47  *  after the SGI SCREEN_SAVER extension was already in use, and resides in
  48  *  .../contrib/extensions/screensaver/ on the X11R6 contrib tape.  It is
  49  *  also found in certain recent X servers built in to NCD X terminals.
  50  *
  51  *     The MIT extension does basically the same thing that the XIDLE extension
  52  *     does, but there are two things wrong with it: first, because of the way
  53  *     the extension was designed, the `fade' option to XScreenSaver will be
  54  *     uglier: just before the screen fades out, there will be an unattractive
  55  *     flicker to black, because this extension blanks the screen *before*
  56  *     telling us that it is time to do so.  Second, this extension is known to
  57  *     be buggy; on the systems I use, it works, but some people have reported
  58  *     X server crashes as a result of using it.  XScreenSaver uses this
  59  *     extension rather conservatively, because when I tried to use any of its
  60  *     more complicated features, I could get it to crash the server at the
  61  *     drop of a hat.
  62  *
  63  *     In short, the MIT-SCREEN-SAVER extension is a piece of junk.  The older
  64  *     SGI SCREEN_SAVER extension works great, as does XIDLE.  It would be nice
  65  *     If those two existed on more systems, that is, would be adopted by the
  66  *     X Consortium in favor of their inferior "not-invented-here" entry.
