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