libinput-magic-mouse

Prerequisites

As of recently, this guide is only written for Ubuntu. But it shouldn't be too hard to adjust for other distributions.

This guide used to be based upon libinput-gestures, but is now using fusuma

Please install fusuma according to its installation guide. In short:

sudo gpasswd -a $USER input
sudo apt install ruby libinput-tools wmctrl libevdev-dev ruby-dev
sudo gem install fusuma fusuma-plugin-wmctrl fusuma-plugin-keypress fusuma-plugin-sendkey

Configuration for fusuma

mkdir -p ~/.config/fusuma
vim ~/.config/fusuma/config.yml

Example configurations are available on the fusuma repository. Mine is included inside this repo. To use it:

cp -v fusuma-config.yml ~/.config/fusuma/config.yml

systemd service for fusuma

place /etc/systemd/system/fusuma.service:

[Unit]
Description=Fusuma
StartLimitIntervalSec=500
StartLimitBurst=5

[Service]
User=jeffrey
Group=jeffrey
Environment="DISPLAY=:0"
ExecStart=/usr/local/bin/fusuma
Type=simple
Restart=on-failure
RestartSec=5s

[Install]
WantedBy=multi-user.target

Obviously, adjust the User and Group settings

And enable the service:

systemctl daemon-reload
systemctl enable --now fusuma.service

Libinput Quirks

In order to get the touchpad to work properly, create the following file:

/etc/libinput/local-overrides.quirks:

[Touchpad touch override]
MatchUdevType=touchpad
MatchName=*Magic Trackpad 2
AttrPressureRange=2:0
AttrTouchSizeRange=20:10

Xorg configuration

Last time I tested the touchpad with KDE Plasma on 20.04 (Neon), I needed to configure the Trackpad through xorg settings

mkdir -p /etc/X11/xorg.conf.d

/etc/X11/xorg.conf.d/10-libinput.conf:
