I'm using a Lenovo ThinkPad T440p as you can see link image below.. I have a problem with the touchpad, it caused the mouse to go crazy on its own. I want to disable certain functionality from the touchpad not the whole touchpad. In this model of ThinkPad the touchpad is used to move the mouse AND to click on things. The goal is to disable the mouse movement ONLY from the touchpad and use it just for clicks(right and left click). To move the mouse I will be using the pointing stick (red dot on the keyboard)

OS: Fedora 33

Unfortunately, your touchpad has a hardware device that communicates with the motherboard as a whole. Some touchpads communicate under i2c standards others under usb standards.

If you disable the driver, you disable the whole thing. Since the comms happens serially, there's no hardware solution to separate touch signals from button signals either.

If your device is not behaving properly, very likely you have the wrong driver installed for your device.

  • how can I identify the driver I'm using and see if it is correct? In some other forum somebody said to use synaptics.conf to isolate the functionality.. would that help?

  • Most modern desktop environments use libinput directly. Gnome for example will allow you to adjust that setting as shown here, drive.google.com/file/d/1w4d0iVt0VUmrHNsI2eGN-Wa1Jqusk3wF/view but I wasn't able to completely disable the touch movement.
