Public bug reported:
The package xserver-xorg-input-synaptics needs to be updated in the
Ubuntu repositories.
I have a Lenovo ThinkPad E460 with a ClickPad. The click pad works perfectly on
Windows10.
On Ubuntu 16.04.1 LTS the mouse behaves properly except when drag and dropping
in the following way:
1) Press left button "under" the clickpad with a finger
2) Move another finger across the touchpad.
When I do that, the mouse simply jumps around to the corners of the
screen. It probably can't tell which finger is moving.
But If I do the following it works:
1) Press left *physical* button (this Thinkpad has physical buttons on top of
the clickpad)
2) Move a finger across the touchpad.
So clearly the problem is with the driver of the clickpad.
The solution I found requires installing xserver-xorg-input-synaptics
version 1.9.0 instead of the 1.8.3 that comes by default with Ubuntu.
When installing that version (taken from Debian Stretch repo) it all
worked again. Note that this version is the same that Fedora 25 ships by
default.
When updating to 1.9.0, a bunch of pacakges needed to get new versions
as well. Listed below:
Upgraded the following packages:
libgcrypt20 (1.6.5-2ubuntu0.2) to 1.7.6-1

It seems the bug is already solved in the package but this package is
not yet available from Ubuntu repositories. Please release it.
