XSET(1X11) COMMAND REFERENCE XSET(1X11) NAME xset - user preference utility for X SYNOPSIS xset [-display display] [-b] [b on/off] [b [volume [pitch [duration]]] [-c] [c on/off] [c [volume]] [[-+]fp[-+=] path[,path[,...]]] [fp default] [fp rehash] [[-]led [integer]] [led on/off] [m[ouse] [acceleration [threshold]]] [m[ouse] default] [p pixel color] [[-]r] [r on/off] [s [length [period]]] [s blank/noblank] [s expose/noexpose] [s on/off] [s default] [q] This is a user-contributed client. DESCRIPTION This program is used to set various user preference options of the display. OPTIONS -display display This option specifies the server to use; see X(1x11). b The b option controls bell volume, pitch and duration. This option accepts up to three numerical parameters, a preceding dash (-), or an 'on/off' flag. If no parameters are given, or the 'on' flag is used, the system defaults will be used. If the dash or 'off' are given, the bell will be turned off. If only one numerical parameter is given, the bell volume will be set to that value, as a percentage of its maximum. Likewise, the second numerical parameter specifies the bell pitch, in hertz, and the third numerical parameter specifies the duration in milliseconds. Note that not all hardware can vary the bell characteristics. The X server will set the characteristics of the bell as closely as it can to the user's specifications. c The c option controls key click. This option can take an optional value, a preceding dash (-), or an 'on/off' flag. If no parameter or the 'on' flag is given, the system defaults will be used. If the dash or 'off' flag is used, keyclick will be disabled. If a value from 0 to 100 is given, it is used to indicate volume, as a percentage of the maximum. The X server will set the volume to Printed 3/22/89 1
XSET(1X11) COMMAND REFERENCE XSET(1X11) the nearest value that the hardware can support. fp= path,... The fp= sets the font path to the directories given in the path argument. The directories are interpreted by the server, not by the client, and are server-dependent. Directories that do not contain font data bases created by mkfontdir will be ignored by the server. fp default The default argument causes the font path to be reset to the server's default. fp rehash The rehash argument causes the server to reread the font data bases in the current font path. This is generally only used when adding new fonts to a font directory (after running mkfontdir to recreate the font data base). -fp or fp- The -fp and fp- options remove elements from the current font path. They must be followed by a comma-separated list of directories. +fp or fp+ The +fp and fp+ options prepend and append elements to the current font path, respectively. They must be followed by a comma-separated list of directories. led The led option controls the keyboard LEDs. This controls the turning on or off of one or all of the LEDs. It accepts an optional integer, a preceding dash (-) or an 'on/off' flag. If no parameter or the 'on' flag is given, all LEDs are turned on. If a preceding dash or the flag 'off' is given, all LEDs are turned off. If a value between 1 and 32 is given, that LED will be turned on or off depending on the existence of a preceding dash. A common LED which can be controlled is the ``Caps Lock'' LED; ``xset led 3'' would turn led #3 on; ``xset -led 3'' would turn it off. The particular LED values may refer to different LEDs on different hardware. m The m option controls the mouse parameters. The parameters for the mouse are `acceleration' and `threshold'. The mouse, or whatever pointer the machine is connected to, will go `acceleration' times as fast when Printed 3/22/89 2
XSET(1X11) COMMAND REFERENCE XSET(1X11) it travels more than `threshold' pixels in a short time. This way, the mouse can be used for precise alignment when it is moved slowly, yet it can be set to travel across the screen in a flick of the wrist when desired. One or both parameters for the m option can be omitted, but if only one is given, it will be interpreted as the acceleration. If no parameters or the flag 'default' is used, the system defaults will be set. p The p option controls pixel color values. The parameters are the color map entry number in decimal, and a color specification. The root background colors may be changed on some servers by altering the entries for BlackPixel and WhitePixel. Although these are often 0 and 1, they need not be. Also, a server may choose to allocate those colors privately, in which case an error will be generated. The map entry must not be a read-only color, or an error will result. r The r option controls the autorepeat. If a preceding dash or the 'off' flag is used, autorepeat will be disabled. If no parameters or the 'on' flag is used, autorepeat will be enabled. s The s option lets you set the screen saver parameters. This option accepts up to two numerical parameters, a 'blank/noblank' flag, an 'expose/noexpose' flag, an 'on/off' flag, or the 'default' flag. If no parameters or the 'default' flag is used, the system will be set to its default screen saver characteristics. The 'on/off' flags simply turn the screen saver functions on or off. The 'blank' flag sets the preference to blank the video (if the hardware can do so) rather than display a background pattern, while 'noblank' sets the preference to display a pattern rather than blank the video. The 'expose' flag sets the preference to allow window exposures (the server can freely discard window contents), while 'noexpose' sets the preference to disable screen saver unless the server can regenerate the screens without causing exposure events. The length and period parameters for the screen saver function determines how long the server must Printed 3/22/89 3
XSET(1X11) COMMAND REFERENCE XSET(1X11) be inactive for screen saving to activate, and the period to change the background pattern to avoid burn in. The arguments are specified in seconds. If only one numerical parameter is given, it will be used for the length. q The q option gives you information on the current settings. These settings will be reset to default values when you log out. Note that not all X implementations are guaranteed to honor all of these options.
