<span class="quote">> ok, that took me a while, but: why is the INPUT_PROP_BUTTONPAD property
> missing?</span >
Fot the archives, the events were recorded on a kernel where RMI4 over SMBus
was incomplete, thus the missing BUTTONPAD property.
With a full RMI4 over SMBus stack, I natively get the property and the software
button dead zone is enough to make the device usable again.
However, as stated in the bug, switching the device to clickfinger is
cumbersome as the pointer jumps when clicking in the bottom part of the
touchpad (with the side of my thumb).</pre>
