.SH NAME
.LP
synclient \- commandline utility to query and modify Synaptics driver
options.
.SH "SYNOPSIS"
.LP
synclient [\fI\-m interval\fP]
.br
synclient [\fI\-hlV?\fP] [var1=value1 [var2=value2] ...]
.SH "DESCRIPTION"
.LP
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.
.SH "OPTIONS"
.LP
.TP
\fB\-m interval\fR
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.
.RS
.TP
\fBtime\fR
Time in seconds since the logging was started.
.TP
\fBx,y\fR
The x/y coordinates of the finger on the touchpad.
.
The origin is in the upper left corner.
.TP
\fBz\fR
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.
.TP
\fBf\fR
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.
.TP
\fBw\fR
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.
.TP
\fBl,r,u,d,m,multi\fR
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.
.TP
\fBgl,gm,gr\fR
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".
.TP
\fBgdx,gdy\fR
Pointer movements from the guest device are reported as relative x/y
positions, called gdx and gdy.
.RE
.TP
\fB\-l\fR
List current user settings.
.TP
\fB\-V\fR
Print version number and exit.
.TP
\fB\-?\fR
Show the help message.
.TP
\fBvar=value\fR
Set user parameter \fIvar\fR to \fIvalue\fR.
.SH "FILES"
.LP
\fI/etc/X11/xorg.conf\fP
.LP
\fI/etc/X11/XF86Config\-4\fP
.SH "EXAMPLES"
.LP
To disable EdgeMotionSpeed:
.LP
synclient EdgeMotionSpeed=0
.LP
To monitor touchpad events (requires SHM):
.LP
synclient \-m 100
.SH "AUTHORS"
.LP
