如何心跳X11屏保？
X11有屏保机制，可以通过xset命令控制。无需从 X11 应用程序内部调用外部命令来禁用或检测屏幕保护程序，如何对屏幕保护程序机制进行检测以防止其关闭显示器？
X11 has a screensaver mechanism that can be controlled by xset command. Without having to invoke the external command to disable or heartbeat the screensaver, from inside my X11 application, how can I heartbeat the screensaver mechanism so to prevent it from shutting down the monitor?

如果在现代 Linux 系统上，首选 FreeDesktop 方法是 ping DBus 接口，特别是 org.freedesktop.ScreenSaver.SimulateUserActivity() 或公开接口的其他部分，具体取决于您的需要。
If this on a modern Linux system, the preferred FreeDesktop method is to ping the DBus interface, specifically
org.freedesktop.ScreenSaver.SimulateUserActivity()or another part of the exposed interface, depending on your needs.以及@Kitsune 建议的 D-Bus 解决方案。您还可以采用某些媒体播放器的方法，定期模拟按下某个键（例如 Alt）。
图腾中的代码： http://git.gnome.org/ browser/totem/tree/lib/totem-scrsaver.c 旨在放入您的代码库（LGPL v2.1）中，并且将使用 D-Bus 接口并使用
XTest合成每 30 秒按一次 Alt 键。As well as the D-Bus solution suggested by @Kitsune. You can also take the approach that some media players do and simulate the pressing of a key (e.g. Alt) at regular intervals.
This code in totem: http://git.gnome.org/browse/totem/tree/lib/totem-scrsaver.c is designed to be dropped into your code base (it's LGPL v2.1) and will use both the D-Bus interface and also use
XTestto synthesize pressing the Alt key every 30s.
