Comment 23 for bug 1641290

Same here with Zenbook UX430UN.
There's a kernel module named elan_i2c that makes me wonder:
modinfo elan_i2c
filename: /lib/modules/4.10.0-xxxx/kernel/drivers/input/mouse/elan_i2c.ko
version: 1.6.2
license: GPL
description: Elan I2C/SMBus Touchpad driver
author: Duson Lin <email address hidden>
srcversion: 775624509AF59206724C275
alias: i2c:elan_i2c
alias: acpi*:ELAN1000:*

alias: acpi*:ELAN0605:*

depends:
intree: Y
vermagic: 4.10.0-38-generic SMP mod_unload

Since the fingerprint sensor is part of the touchpad, it could be managed by this module (?). But in my configuration this is not loaded by default, and it is loaded instead hid_multitouch.ko.
Unfortunately neither load this manually and remove hid_multitouch resolves.

Hope this helps
