Review of Linux Compatibility
The Logitech T650 Touchpad can be used under Linux, but not all gestures are currently recognized.
Gestures like two-finger scrolling and forward/backward are supported in the web browser. However, most of the gestures that are supported under Windows are not recognized by the X-server and are not available to xev. Hence, these gestures can not be configured under Linux, i.e., the “Pinch-to-Zoom” gesture with more than two fingers is not working, as well as the very basic gesture “Tab-to-Click” is nor recognized.
