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: 25a84db15b3f3a2
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.
The maintainer has provided a patch set to fix this issue and add proper palm detection support and the patch set has been merged. We also need to introduce this feature to Vivid at OEM's demands.
