xmonad 0.7 (Default branch)
03-30-2008
xmonad is a tiling window manager for X. Windows are arranged automatically to tile the screen without gaps or overlap, maximising screen use. Window manager features are accessible from the keyboard; a mouse is optional. xmonad is extensible in Haskell, allowing for powerful customisation. Custom layout algorithms, key bindings, and other extensions may be written by the user in config files. Layouts are applied dynamically, and different layouts may be used on each workspace. Xinerama is fully supported, allowing windows to be tiled on several physical screens. License: BSD License (revised) Changes:|

XSetScreenSaver() XSetScreenSaver() Name XSetScreenSaver - set the parameters of the screen saver. Synopsis XSetScreenSaver(display, timeout, interval, prefer_blanking, allow_exposures) Display *display; int timeout, interval; int prefer_blanking; int allow_exposures; Arguments display Specifies a connection to an X server; returned from XOpenDisplay(). timeout Specifies the time of inactivity, in seconds, before the screen saver turns on. interval Specifies the interval, in seconds, between screen saver invocations. This is for intermittent changes to the display, not blanking. prefer_blanking Specifies whether to enable screen blanking. Possible values are DontPreferBlanking, PreferBlanking, or DefaultBlanking. allow_exposures Specifies the current screen saver control values. Possible values are DontAllowExposures, AllowExposures, or DefaultExposures. Description XSetScreenSaver() sets the parameters that control the screen saver. timeout and interval are specified in seconds. A positive timeout enables the screen saver. A timeout of zero (0) disables the screen saver, while a timeout of -1 restores the default. An interval of zero (0) disables the random pattern motion. If no input from devices (keyboard, mouse, etc.) is generated for the specified number of timeout seconds, the screen saver is activated. For each screen, if blanking is preferred and the hardware supports video blanking, the screen will simply go blank. Otherwise, if either exposures are allowed or the screen can be regenerated without sending exposure events to clients, the screen is tiled with the root window background tile, with a random origin, each interval seconds. Otherwise, the state of the screen does not change. All screen states are restored at the next input from a device. If the server-dependent screen saver method supports periodic change, interval serves as a hint about how long the change period should be, and a value of zero (0) hints that no periodic change should be made. Examples of ways to change the screen include scrambling the color map periodically, moving an icon image about the screen periodically, or tiling the screen with the root window background tile, randomly reoriginated periodically. For more information on the screen saver, see Volume One, Chapter 15, Other Programming Techniques. Errors BadValue timeout < -1.
