Title:
  Enable full touch support for ELAN0600 touchpad

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  ELAN0600 lacks full touch support if not registered with elan_i2c.ko.
  I've got in touch with Benjamin Tissoires, who kindly provided me with a two-lines patch that fixed the problem for my Lenovo Yoga 3 11 [1]. He has afterwards made the patch publicly available at LKML [2].

  
  Some more information follow, the bug is still reproducible with the latest Vivid's and mainline kernels:
