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 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 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 touchpads 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.





To disable EdgeMotionSpeed:

synclient EdgeMotionSpeed=0

To monitor touchpad events (requires SHM):

synclient -m 100
