.Sh NAME
|
|
.Nm atp
|
|
.Nd Apple touchpad driver
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel, place the following lines into
|
|
your kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device atp"
|
|
.Cd "device usb"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
atp_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the Apple Internal Trackpad device found in many
|
|
Apple laptops.
|
|
Older (Fountain/Geyser) and the newer (Wellspring) trackpad
|
|
families are all supported through a unified driver.
|
|
.Pp
|
|
The driver simulates a three\-button mouse using multi\-finger tap detection.
|
|
Single finger tap generates a left\-button click; two\-finger tap maps to the
|
|
middle button; whereas a three\-finger tap gets treated as a right button
|
|
click.
|
|
.Pp
|
|
There is support for 2\-finger horizontal scrolling, which translates to
|
|
page\-back/forward events; vertical multi\-finger scrolling emulates the mouse
|
|
wheel.
|
|
.Pp
|
|
A double\-tap followed by a drag is treated as a selection gesture; a
|
|
virtual left\-button click is assumed for the lifespan of the drag.
|
|
.Pp
|
|
.Nm
|
|
supports dynamic reconfiguration using
|
|
.Xr sysctl 8 ;
|
|
through nodes under
|
|
.Nm hw.usb.atp .
|
|
Pointer sensitivity can be controlled using the sysctl tunable
|
|
.Nm hw.usb.atp.scale_factor .
|
|
Smaller values of
|
|
.Fa scale_factor
|
|
result in faster movement.
|
|
.
|
|
A simple high-pass filter is used to reduce contributions
|
|
from small movements; the threshold for this filter may be controlled by
|
|
.Nm hw.usb.atp.small_movement .
|
|
.
|
|
The maximum tolerable duration of a touch gesture is controlled by
|
|
.Nm hw.usb.atp.touch_timeout
|
|
(in microseconds); beyond this period, touches are considered to be slides.
|
|
(This conversion also happens when a finger stroke accumulates at least
|
|
.Nm hw.usb.atp.slide_min_movement
|
|
movement (in mickeys).
|
|
.
|
|
The maximum time (in microseconds) to allow an association between a double-
|
|
tap and drag gesture may be controlled by
|
|
.Nm hw.usb.atp.double_tap_threshold .
|
|
.
|
|
Should one want to disable tap detection and rely only upon physical button
|
|
presses, set the following sysctl to a value of 2
|
|
.Nm hw.usb.atp.tap_minimum .
|
|
.

To discover the product\-id of a touchpad, search for 'Trackpad' in the
|
|
output of
|
|
.Xr lshal 1
|
|
and look up the property
|
|
.Nm usb_device.product_id .
|
|

|
|
.Nm
