Bug description:
Sometimes touchpad doesn't work properly after palm is rejected. The
pointer either jumping around (described on bugzilla[1]) or doesn't
move at all (in our cases).
This problem is introduced with commit:
25a84db15b3f3a24d3ea7d2baf90693bcff34b0c (HID: multitouch: enable palm
rejection if device implements confidence usage), by reverting it the
touchpad can work properly.
We also contacted with Synaptics, and they provided a workaround to
fix this issue. Not sure if the workaround will be upstreamed and
needs to keep co-working with them.
Commit 25a84db applies to Xenial and Yakkety so only these two release
were affected.
