                          XSET.EXE

Xset is a user preference utility for X. You can use xset to set
various user preference options of the display.

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]

OPTIONS: 

-display display
This option specifies the server to use.
 
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.

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.

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 databases created by mkfntdir 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 databases
in the current font path.  This is generally used only when adding
new fonts to a font directory (after running mkfntdir 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
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 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 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.
