.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.
|
||
|
|
.Pp
|
||
|
|
The driver simulates a three\-button mouse using multi\-finger tap
|
||
|
|
detection.
|
||
|
|
.
|
||
|
|
A 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.
|
||
|
|
.
|
||
|
|
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.
|
||
|
|
.
|
||
|
|
.Nm
|
||
|
|
attempts to filter away activity at the horizontal edges of the
|
||
|
|
trackpad\-\-this is to keep unintentional palm movement from being
|
||
|
|
considered as user input.
|
||
|
|
.
|
||
|
|
.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 .
|
||
|
|
.
|
||
|
|
.Sh HARDWARE
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
driver provides support for the following Product IDs:
|
||
|
|

17 inch PowerBook (ID: 0x020d)
|
||
|
|
.El
|
||
|
|
.Pp
|
||
|
|
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 .
|
||
|
|
.Sh FILES
|
||
|
|
.Nm
|
||
|
|
creates a blocking pseudo\-device file,
|
||
|
|
.Pa /dev/atp0 ,
|
||
|
|
which presents the mouse as a
|
||
|
|
.Ar sysmouse
|
||
|
|
or
|
||
|
|
.Ar mousesystems
|
||
|
|
type device\-\-see
|
||
|
|
.Xr moused 8
|
||
|
|
for an explanation of these mouse
|
||
|
|
types.
|
||
|
|
.Xr moused 8
|
||
|
|
can be configured to read touchpad data from
|
||
|
|
.Pa /dev/atp0
|
||
|
|
and pass it along to the
|
||
|
|
.Xr sysmouse 4
|
||
|
|
driver so that any process wanting to utilize mouse operation (such as
|
||
|
|
an X server) may fetch it from
|
||
|
|
.Pa /dev/sysmouse ;
|
||
|
|
alternatively,
|
||
|
|
.Pa /dev/atp0
|
||
|
|
may be manipulated via
|
||
|
|
.Xr read 2
|
||
|
|
and
|
||
|
|
.Xr ioctl 2
|
||
|
|
calls to get mouse data directly.
|
||
|
|
.Sh EXAMPLES
|
||
|
|
To use a compatible Apple Trackpad as your console mouse:
|
||
|
|
.Pp
|
||
|
|
.Dl moused -p /dev/atp0 -t auto
|
||
|
|
.Pp
|
||
|
|
To launch
|
||
|
|
.Xr moused 8
|
||
|
|
automatically upon boot, add the following to
|
||
|
|
.Pa /etc/rc.conf :
|
||
|
|
.Pp
|
||
|
|
.Dl moused_enable="YES"
|
||
|
|
.Dl moused_type="auto"
|
||
|
|
.Dl moused_port="/dev/atp0"
|
||
|
|
.Pp
|
||
|
|
If you want
|
||
|
|
.Xr moused 8
|
||
|
|
to also probe for external USB mice or other devices, then add the
|
||
|
|
following to
|
||
|
|
.Pa /etc/rc.conf :
|
||
|
|
.Pp
|
||
|
|
.Dl moused_nondefault_enable="YES"
|
||
|
|
.Dl moused_ums0_enable="YES"
|
||
|
|
.Dl moused_ums1_enable="YES"
|
||
|
|
.Pp
|
||
|
|
To be able to use the trackpad under X, change the "Pointer" section in
|
||
|
|
.Nm xorg.conf
|
||
|
|
to the following:
|
||
|
|
.Pp
|
||
|
|
.Dl Device "/dev/atp0"
|
||
|
|
.Dl Protocol "Auto"
|
||
|
|
.Pp
|
||
|
|
Better still, if you want to be able to use the mouse in both virtual
|
||
|
|
consoles as well as in X change it to:
|
||
|
|
.Pp
|
||
|
|
.Dl Device "/dev/sysmouse"
|
||
|
|
.Dl Protocol "Auto"
|
||
