Public bug reported: 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.
