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.
-l List current user settings. This is the default if no option is given.
-V Print version number and exit.

var=value Set user parameter var to value.

To disable EdgeMotionSpeed:
synclient EdgeMotionSpeed=0
To monitor touchpad events (requires SHM):
synclient -m 100
