Touchpad of Yoda2 doesn't work well via PS/2 mode, most time the data is
lost sync via PS/2.

I have made a patch in upstream/Ubuntu 4.15/4.13 kernels to force
touchpad using SMBus mode.
SMBus mode requires i2c-i801 kernel module which is in modprobe
blacklist in Ubuntu 18.04/16.04. User has to remove i2c-i801 manually.

i2c-i801 in blacklist is a very old workaround to fix HP compaq nc6000
(Bug #10306), this module should be removed from blacklist.
