       synclient  -  commandline  utility to query and modify Synaptics driver


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


       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.


       -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 touchpads 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.   Generally,  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

                     The state of the left, right, up, down, middle and  multi
                     buttons.  Zero means not pressed, one means pressed.  Not
                     all touchpads  have  all  these  buttons.   If  a  button
                     doesn’t exist, the value is always reported as 0.

                     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".

                     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.

              Set user parameter var to value.





       To disable EdgeMotionSpeed:

       synclient EdgeMotionSpeed=0

       To monitor touchpad events (requires SHM):

       synclient -m 100
