This repository contains the linux hid-magicmouse driver with Magic Trackpad 2 and Magic Mouse 2 support for Linux 4.18. For older kernels you might have to diff and backport.
This driver is based off of the work of @robotrovsky, @svartalf and probably others.
The driver is tested in combination with the xf86-libinput and xf86-mtrack driver.
Please help to test this driver and report issues.
The driver supports bluetooth and USB for the trackpad. To connect the Trackpad via bluetooth, it must be clicked once after it is turned on, then the Trackpad tries to reconnect to the last paired (and trusted) connection.
The drivers supports regular mouse motion and additionally scrolling and mouse middle click. Middle click is a single finger click near the middle portion of the touch surface OR a 3 finger click anywhere on the touch surface if you put the mouse in 3 finger middle click mode (instructions on how to do this are in the installation section. If you like this, please let me know so I can make it the default). Scrolling is a single finger up or down motion anywhere on the touch surface.
You can just use the standard xf86-libinput driver and configure it through your Window-Manager-Settings. This driver works very well, but does not support three-finger-drag, but tap-to-drag.
An example configuration for mtrack can be found in:
usr/share/X11/xorg.conf.d/90-magictrackpad.conf
This configuration supports tap-to-click, two-finger-scroll and three-finger-drag. Though scrolling is not as smooth as with xf86-libinput. It can be used as starting point for your own configuration. Make sure, that you have xf86-input-mtrack-git installed and it gets loaded. You find more information about the options here: https://github.com/p2rkw/xf86-input-mtrack
@adam-h made a DKMS which can be used for testing:
Setup/install with:
You will need a 4.18 or above kernel.
sudo apt-get install dkms
git clone https://github.com/rohitpid/Linux-Magic-Trackpad-2-Driver.git
cd Linux-Magic-Trackpad-2-Driver/scripts
chmod u+x install.sh
sudo ./install.sh
If you want test out 3 finger middle click feature (please do)
cd Linux-Magic-Trackpad-2-Driver/linux/drivers/hid
make clean
make
sudo rmmod hid-magicmouse
sudo insmod ./hid-magicmouse.ko middle_click_3finger=1
Remove with:
sudo ./remove.sh
Or just use regular dkms commands once you've added ./linux/drivers/hid.
If the driver is not working, please make sure that the correct hid-magicmouse driver gets loaded and try the following steps:
cd linux/drivers/hid
make
sudo rmmod hid_magicmouse
sudo insmod ./hid-magicmouse.ko
tail -f ~/.local/share/xorg/Xorg.0.log
Now unplug the trackpad and plug it back in, to see which driver gets loaded.
/* The data layout for magic mouse 2 is:
* 14 bytes of prefix
* data[0] is the device report ID
* data[1] is the mouse click events. Value of 1 is left, 2 is right.
* data[2] (contains lsb) and data[3] (msb) are the x movement
* of the mouse 16bit representation.
* data[4] (contains msb) and data[5] (msb) are the y movement
* of the mouse 16bit representation.
* data[6] data[13] are unknown so far. Need to decode this still
*
* data[14] onwards represent touch data on top of the mouse surface
* touchpad. There are 8 bytes per finger. e.g:
* data[14]-data[21] will be the first finger detected.
* data[22]-data[29] will be finger 2 etc.
* these sets of 8 bytes are passed in as tdata to
* magicmouse_emit_touch()
*
* npoints is the number of fingers detected.
* size is minimum 14 but could be any multpiple of 14+ii*8 based on
* how many fingers are detected. e.g for 1 finger, size=22 for
* 2 fingers, size=30 and so on.

/* tdata is 8 bytes per finger detected.
