magictrackpad2-dkms
A DKMS module for patching the bcm5974 and hid drivers to support the Apple Magic Trackpad 2.
Tested with Kernel 4.4.0-57-generic on Ubuntu 16.04 LTS.
How to install
It should be enough to install the package. If it still doesn't work, you may have to copy the kernel modules from
/lib/modules/4.4.0-57-generic/updates/dkms/
to /lib/modules/4.4.0-57-generic/kernel/drivers/hid/
How to configure
Configuration happens in xorg.conf
at
/usr/share/X11/xorg.conf.d/49-synaptics-bcm5974.conf
and with xinput
.
If your mouse only moves when you press hard, modify the thresholds:
xinput set-prop "bcm5974" "Synaptics Finger" 0 10 0
How to update
Install the current kernel sources: sudo apt-get install linux-source
The sources are then available at /usr/src/linux-source-4.4.0/linux-source-4.4.0.tar.bz2
.
Extract following files to src/bcm5974...
:
/linux-source-4.4.0/drivers/input/mouse/bcm5974.c
Extract following files to src/hid...
:
/linux-source-4.4.0/drivers/hid/hid-apple.c
