This repository contains the linux hid-magicmouse driver with Magic Trackpad 2 support for Linux 4.18. For older kernels you might have to diff and backport.
The driver is tested in combination with the xf86-libinput and xf86-mtrack driver.
The driver supports bluetooth and USB. 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.
Please help to test this driver and report issues.
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:
cd scripts
sudo ./install.sh
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.
