This file handles all of the default gestures on installing Touchégg.

This file contains a combination of meta information resources and a shortcut to the Touchégg application, in accordance with the XDG Desktop Entry specification which defines a standard for applications to integrate into application menus of desktop environments.

This file is installed into the system-wide XDG Autostart directory (/etc/xdg/autostart), which allows autostarting ordinary desktop entries on desktop environment startup.

This service runs Touchégg in daemon mode (touchegg --daemon) as part of the "input" group. The daemon will open a Unix domain socket so any service (usually touchegg --client) can have access to libinput's multi-touch gestures.

CMake configures the path for ExecStart and saves the result in touchegg.service.

Change the ExecStart to your binary path:
