description
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.
options
-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.
-?
Show the help message.
var=value
Set user parameter var
to value.
