^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) appletouch is a Linux kernel driver for the USB touchpad found on post
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) February 2005 and October 2005 Apple Aluminium Powerbooks.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) This driver is derived from Johannes Berg's appletrackpad driver [#f1]_,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) but it has been improved in some areas:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) * appletouch is a full kernel driver, no userspace program is necessary
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) * appletouch can be interfaced with the synaptics X11 driver, in order
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) to have touchpad acceleration, scrolling, etc.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) Credits go to Johannes Berg for reverse-engineering the touchpad protocol,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) Frank Arnold for further improvements, and Alex Harper for some additional
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) information about the inner workings of the touchpad sensors. Michael
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) Hanselmann added support for the October 2005 models.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) Usage
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) -----
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) In order to use the touchpad in the basic mode, compile the driver and load
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) the module. A new input device will be detected and you will be able to read
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) the mouse data from /dev/input/mice (using gpm, or X11).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) In X11, you can configure the touchpad to use the synaptics X11 driver, which
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) will give additional functionalities, like acceleration, scrolling, 2 finger
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) tap for middle button mouse emulation, 3 finger tap for right button mouse
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) emulation, etc. In order to do this, make sure you're using a recent version of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) the synaptics driver (tested with 0.14.2, available from [#f2]_), and configure
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) a new input device in your X11 configuration file (take a look below for an
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) example). For additional configuration, see the synaptics driver documentation::

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 69) -------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 70)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 71) The touchpad sensors are very sensitive to heat, and will generate a lot of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 72) noise when the temperature changes. This is especially true when you power-on
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 73) the laptop for the first time.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 74)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 75) The appletouch driver tries to handle this noise and auto adapt itself, but it
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 76) is not perfect. If finger movements are not recognized anymore, try reloading
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 77) the driver.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 78)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 79) You can activate debugging using the 'debug' module parameter. A value of 0
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 80) deactivates any debugging, 1 activates tracing of invalid samples, 2 activates
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 81) full tracing (each sample is being traced)::
