If you do not need the newer kernel then it would be wise to go back to one that worked. The problem with going to far up the kernel chain is that the higher the kernel number the newer the hardware it only supports. I had all sorts of issues with the 4.13 and higher on this old laptop but staying at 4.10 series works fine. Please tell what addition to the grub.conf you did that threw the errors and disables your mouse and touchpad.
