The new version 3.14 of the GNOME desktop now supports multitouch gestures natively. (see e.g. Multi-touch gestures in GNOME 3.14)
How can I deactivate this feature?
I would like to continue using my touchegg setup, where I can customize and assign gestures in any way I like. But touchegg can no longer subscribe to the gestures on the root window if gnome-panel already did so.
