synclient - commandline utitlity 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
