Thanks for the quick reply. Unfortunately this does not change anything (also did a reboot to be sure).

It is essentially unusable. * The touchpad starts with parameters set incorrectly. * Touchpad tap to click is now turned on again and is very sensitive. This I can change through xinput but the change is still odd. * The two finger scrolling is set incorrectly to be highly sensitive. This I can also change through xinput. * Two finger scrolling still activates often during normal use of the trackpad. To the extent that I had to turn off two finger scrolling to stop inadvertent scrolling. All of the above behavior is new going from 4.4.0-47 to -53. Previously this all worked perfectly on this machine. Seems to be symptoms noted by these other users on askubuntu here as well: http://askubuntu.com/questions/862527/laptop-stick-mouse- problems-after-linux-4-4-update-on-14-04 The touchpad symptoms I seem to be able to work around my changing xinput parameters, but the trackpoint I have not been able to fix at all (which is sad since that is my primary mouse device normally). Would appreciate any suggestions as to how to revert the old behavior.
