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.
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
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.
