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 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-
fications.
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
work.
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
hardware.
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.
