Bug Description

Lenovo ideapad 730s touchpad wrist detection does not work.
I have tried both synaptics and libinput drivers. The libinput driver's scroll coasting does not work. With the synaptics driver, using synclient to set PalmDetect=1 has no effect.
In KDE's touchpad settings, pressure-dependant motion, sensitivity, and palm detection are all greyed out.

I am running kubuntu 20.10 and the 5.11 kernel.
