Title:
  Lenovo X1C6 trackpad functions broken

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Summary:
  After kernel update the trackpad advanced functions, like two finger 
scrolling and mouse acceleration have stopped working.

  Expected Result:
  Two finer scroll works and the mouse has acceleration features work

  Actual Result:
  Two finer scroll works and the mouse has acceleration features do not work

  Steps to reproduce:
  1. Lenovo X1C6 (LENOVO 20KHCTO1WW/20KHCTO1WW, BIOS N23ET59W (1.34 ) 
11/08/2018)
  2. Install 18.04 LTS
  3. config-4.15.0-42-generic acceleration works, while 
config-4.15.0-43-generic does not

  This appears to be some sort of regression or change in behavior between 
kernel versions.
