Title:
  Palm rejection for MS Precision Touchpad causes touchpad unusable

Status in HWE Next:

Status in HWE Next xenial series:
  Confirmed
Status in HWE Next yakkety series:
  New
Status in Linux:

  Confirmed

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.
