NAME

       synclient - commandline utility to query and modify Synaptics driver options.

SYNOPSIS

       synclient [-m interval]
       synclient [-hlV?] [var1=value1 [var2=value2] ...]

DESCRIPTION

       This program lets you change your Synaptics TouchPad driver for XOrg/XFree86 server parameters while X is running.

       For the -m and -h options, SHM must be enabled by setting the option SHMConfig "on" in your XOrg/XFree86 configuration.

OPTIONS

       -m interval
	      monitor  changes	to the touchpad state.	Interval specifies how often (in ms) to poll the touchpad state.  Whenever a change in the
	      touchpad state is detected, one line of output is generated that describes the current state of the touchpad.  This option  is  only
	      available in SHM mode.  The following data is included in the output.

	      time   Time in seconds since the logging was started.

	      x,y    The x/y coordinates of the finger on the touchpad.  The origin is in the upper left corner.

	      z      The  "pressure"  value.  Pressing the finger harder on the touchpad typically produces a larger value.  Note that most touch-
		     pads don't measure the real pressure though.  Instead, capacitance is usually measured, which is correlated  to  the  contact
		     area  between  the  finger  and the touchpad.  Since more pressure usually means a larger contact area, the reported pressure
		     value is at least indirectly related to the real pressure.

	      f      The number of fingers currently touching the touchpad.  Note that only some touchpads can report more than one finger.   Gen-
		     erally, synaptics touchpads can, but ALPS touchpads can't.

	      w      The  w value is a measurement of the finger width.  This is only supported by some synaptics touchpads.  Touchpads that can't
		     measure the finger width typically report a faked constant value when a finger is touching the touchpad.

	      l,r,u,d,m,multi
		     The state of the left, right, up, down, middle and multi buttons.	Zero means not pressed, one means pressed.  Not all touch-
		     pads have all these buttons.  If a button doesn't exist, the value is always reported as 0.

	      gl,gm,gr
		     Some  touchpads have a "guest device".  This is typically a pointing stick located in the middle of the keyboard.	Some guest
		     devices have physical buttons, or can detect button presses when tapping on the  pointing	stick.	 Such  button  events  are
		     reported as "guest left", "guest middle" or "guest right".

	      gdx,gdy
		     Pointer movements from the guest device are reported as relative x/y positions, called gdx and gdy.

       -l     List current user settings.

       -V     Print version number and exit.

       -?     Show the help message.

       var=value
	      Set user parameter var to value.

EXAMPLES

       To disable EdgeMotionSpeed:

       synclient EdgeMotionSpeed=0

       To monitor touchpad events (requires SHM):

       synclient -m 100
