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