>Subject: [PATCH libinput] udev: add the T440p to the T450 jumping motion
> quirks
>
>On slow finger motion, this device also sends a bunch of events with only
>pressure updates, followed by a massive coordinate jump. Enable the quirk so
>we skip that jump. This is for RMI4 and PS/2, RMI4 is confirmed in the bug
>below, let's assume PS/2 has that issue too.
