OPTIONS
-display display
This option specifies the server to use; see X(1X).
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
Enables the VESA Display Power Management Signalling (DPMS) features of
the X Server regardless of the operating system's power management
state. It is unnecessary to enable DPMS mode with +dpms when using the
dpms switch to change the dwell times or the dpms force switch to force
a mode, since those switches will automatically enable the DPMS
features of the X Server. DPMS mode defaults are dictated by the
kernel's power management subsystem. DPMS should only be enabled for
systems with DPMS-compliant hardware.
-dpms
Disables the VESA DPMS features of the X Server regardless of the
operating system's power management state. DPMS mode defaults are
dictated by the kernel's power management subsystem.
dpms standby-time suspend-time off-time
Enables the VESA DPMS features of the XServer and defines dwell times
for it, regardless of the operating system's power management state.
Specify the number of seconds to wait before starting each particular
mode. All three values must be supplied and each subsequent value must
be greater than or equal to the next, with the exception of 0. A value
of 0 will disable a particular mode and it is independent of the other
dwell times. For instance, if the value for standby mode is 300
seconds, the value for suspend mode can be 0 seconds, but the value for
off mode must be greater than or equal to 300 seconds. DPMS default
dwell times are dictated by the kernel's power management subsystem.
dpms force mode
Enables the VESA DPMS features of the XServer and forces a particular
mode, effective immediately. Possible modes include on, standby,
suspend, and off.
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. The entire font path must be valid; if any element
is invalid, the path is rejected.
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. The entire
font path must be valid; if any element is invalid, the path is
rejected.
+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
entries. The entire font path must be valid; if any element is
invalid, the path is rejected.
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.
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.
