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)

kernel versions.
