Comment 12 for bug 1778087

I had this same problem with my laptop on 17.10. When I upgraded to the kernel to 4.14 I did not receive the errors in the syslog, but the touchpad responsiveness and functionality worked fine.
When I upgraded to 18.04 with kernel 4.15.0-24 it looks like it has regressed and I am back to using a USB mouse since the touchpad is almost unusable, and if I put all 5 fingers on the touchpad, it locks it out completely.
