DESCRIPTION
       This program is used to set various user preference options of the dis-
       play.

OPTIONS
       -display display
	       This option specifies the server to use; see X(7).


       b       The  b  option  controls bell volume, pitch and duration.  This
	       option accepts up to three numerical  parameters,  a  preceding
	       dash(-),	 or  a	'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.


       bc      The bc option controls bug compatibility mode in the server, if
	       possible;  a preceding dash(-) disables the mode, otherwise the
	       mode is enabled.	 Various pre-R4 clients pass illegal values in
	       some  protocol  requests,  and pre-R4 servers did not correctly
	       generate errors in these cases.	Such clients, when run against
	       an  R4  server,	will terminate abnormally or otherwise fail to
	       operate correctly.  Bug compatibility mode explicitly  reintro-
	       duces certain bugs into the X server, so that many such clients
	       can still be run.  This mode should  be	used  with  care;  new
	       application development should be done with this mode disabled.
	       The server must	support	 the  MIT-SUNDRY-NONSTANDARD  protocol
	       extension in order for this option to work.

       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 the nearest value that the hardware can
	       support.


       -dpms   The -dpms option disables DPMS (Energy Star) features.

       +dpms   The +dpms option enables DPMS (Energy Star) features.

       dpms flags...
	       The dpms option allows the DPMS (Energy Star) parameters to  be
	       set.   The option can take up to three numerical values, or the
	       'force' flag followed by	 a  DPMS  state.   The	'force'	 flags
	       forces the server to immediately switch to the DPMS state spec-
	       ified.  The DPMS state can  be  one  of	'standby',  'suspend',
	       'off',  or 'on'.	 When numerical values are given, they set the
	       inactivity period (in units of seconds) before the three	 modes
	       are  activated.	 The  first  value  given is for the 'standby'
	       mode, the second is for the 'suspend' mode, and	the  third  is
	       for  the	 'off'	mode.  Setting these values implicitly enables
	       the DPMS features.  A value of zero disables a particular mode.

       fp= path,...
	       The  fp=	 sets  the  font path to the entries given in the path
	       argument.  The entries are interpreted by the  server,  not  by
	       the  client.  Typically they are directory names or font server
	       names, but the interpretation is server-dependent.

       fp default
	       The default argument causes the font path to be	reset  to  the
	       server's default.

       fp rehash
	       The  rehash argument resets the font path to its current value,
	       causing the server to reread the font databases 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 database).


       -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
	       entries.


       +fp or fp+
	       This  +fp  and  fp+  options prepend and append elements to the
	       current font path, respectively.	 They must be  followed	 by  a
	       comma-separated list of entries.


       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 pre-
	       ceding 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 acceleration
	       can  be	specified as an integer, or as a simple fraction.  The
	       mouse, or whatever pointer the machine is connected to, will go
	       'acceleration' times as fast when it travels more than 'thresh-
	       old' 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 omit-
	       ted, 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 specifica-
	       tion.  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.	Invoking with "-r", or
	       "r off", will disable autorepeat, whereas "r", or  "r on"  will
	       enable  autorepeat.   Following	the "-r" or "r" option with an
	       integer keycode between	0  and	255  will  disable  or	enable
	       autorepeat on that key respectively, but only if it makes sense
	       for the particular keycode.  Keycodes below 8 are not typically
	       valid  for  this	 command.   Example: "xset -r 10" will disable
	       autorepeat for the "1" key on the top row of  an	 IBM  PC  key-
	       board.

	       If  the	server supports the XFree86-Misc extension, or the XKB
	       extension, then a parameter of 'rate' is accepted and should be
	       followed	 by  zero, one or two numeric values. The first speci-
	       fies the delay before autorepeat starts and the	second	speci-
	       fies the repeat rate.  In the case that the server supports the
	       XKB extension, the delay is the number of  milliseconds	before
	       autorepeat  starts,  and	 the rate is the number of repeats per
	       second.	If the rate or delay is not given, it will be  set  to
	       the default value.


       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, an 'activate/reset' 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
	       'activate' flag forces activation of screen saver even  if  the
	       screen  saver  had  been	 turned	 off.  The 'reset' flag forces
	       deactivation of screen saver if it is active.  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 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.
