       This program is used to set various user preference options of the display.

       -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 param-
	       eters 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	millisec-
	       onds.  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 speci-

       bc      The  bc	option controls bug compatibility mode in the server, if possible; a pre-
	       ceding 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 reintroduces 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

       c       The c option controls key click.  This option can take an optional value,  a  pre-
	       ceding  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 specified.  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 recre-
	       ate 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 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

       mouse   The m option controls the mouse parameters; it may be  abbreviated  to  'm'.   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 `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.

	       If  the `threshold' parameter is provided and 0, the `acceleration' parameter will
	       be used in the exponent of a more natural and continous	formula,  giving  precise
	       control for slow motion but big reach for fast motion, and a progresive transition
	       for motions in between.	Recommended `acceleration' value in this case is  3/2  to
	       2, but not limited to that range.

       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.  Invoking with "-r", or "r off",  will  dis-
	       able  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 keyboard.

	       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 specifies the delay before  autorepeat  starts  and  the  second
	       specifies  the  repeat  rate.  In the case that the server supports the XKB exten-
	       sion, 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.
