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

       -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

       -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

       -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

       +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.
               ``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.  If the X server supports the XKEYBOARD (XKB)
               extension, leds may be referenced by the XKB indicator name by
               specifying the `named' keyword and the indicator name.   For
               example, to turn on the Scroll Lock LED:

               xset led named "Scroll Lock"

       mouse   The m option controls the mouse parameters; it may be abbreviated
               to 'm'. Of course, it applies to most pointing devices, not just
               mice. The parameters for the pointing device are `acceleration'
               and `threshold'. The acceleration can be specified as an integer,
               or as a simple fraction. Threshold is just an integer. The
               setting is applied to all connected pointing devices. xinput(1)
               should be used if you need device-specific settings.

       By default the pointer (the on-screen representation of the pointing
       device) will go `acceleration' times as fast when the device travels more
       than `threshold' mickeys (i.e. would-be pixels) in 10 ms, including a
       small transition range. This way, the pointing device 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 continuous
       formula, giving precise control for slow motion but big reach for fast
       motion, and a progressive transition for motions in between.  Recommended
       `acceleration' value in this case is 3/2 to 3, but not limited to that

       In the X.org X Server 1.6 and above, the behaviour described so far is
       linked to the default profile. There are other profiles (i.e. functions
       determining pointer acceleration from device velocity) and additional
       settings, so the above description may not apply to non-default cases. In
       the X.org Server 1.7, these are available as input device properties (see

       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 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 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
               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.

               The -version option prints the program version and exits without
               doing anything else.

       These settings will be reset to default values when you log out.
