I withdraw my complaint. I updated the bios and installed a new OS
partition and this new kernel works much better now. I fear that I had
tried to adjust miscellaneous settings so much in the past 2 months that
my fixes were blocking the beneficial changes. I had put a blacklist
line on i2c_hid before and I suspect that was preventing the change from
taking effect.
$ sudo dmidecode -s bios-version

I stopped using synclient entirely, am using libinput with only a minor
change in X11/xorg.conf.d, just the very last line of this:
$ cat /etc/X11/xorg.conf.d/90-libinput.conf
# Match on all types of devices but tablet devices and joysticks
Section "InputClass"
Identifier "libinput pointer catchall"
MatchIsPointer "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
EndSection
Section "InputClass"
Identifier "libinput keyboard catchall"
MatchIsKeyboard "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
EndSection
Section "InputClass"
Identifier "libinput touchpad catchall"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
EndSection
Section "InputClass"
Identifier "libinput touchscreen catchall"
MatchIsTouchscreen "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
EndSection
Section "InputClass"
Identifier "MyTouchpad"
MatchIsTouchpad "on"
Driver "libinput"
Option "Tapping" "on"
EndSection
I no longer see the frequent accidental select and delete behavior I was seeing
in editors like Emacs and LyX.
The only problem I see now is that, while using Gimp, the cursor fairly
often flies to the bottom and points at the desktop panel.

Title:
Add proper palm detection support for MS Precision Touchpad
Status in HWE Next:
Confirmed
Status in HWE Next xenial series:
Confirmed
Status in Linux:
Unknown
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Xenial:
Fix Committed
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.
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.
