Hi, I am experiencing a similar problem as Gianluigi on my Lenovo X1 Extreme Gen 2 running Debian Testing with Gnome where touchpad click is non-responsive while running kernel 5.10.
There is no response whatsoever to clicking the touchpad, and the pointer does not respond when one finger taps and holds or clicks and holds and another finger drags across the touch pad.
