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

71 * lets XScreenSaver work better with servers which support this extension;
72 * but it will still work with servers which do not suport it, so it's a good
73 * idea to compile in support for it if you can.
