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


       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

              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.

       -l     List current user settings. This is the default if no option is given.

       -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
