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(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
               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 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
               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 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
               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 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.

       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.  If a specific keycode is specified as a parameter,
               autorepeat for that keycode is enabled or disabled.  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 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.

               Example: The following command will set the delay to 200
               milliseconds and the repeat rate to 10 per second:

                   xset r rate 200 10

       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.
