So for what it's worth looking at adopting libinput would likely improve your touchpad experience.
You should investigate if you are using that after upgrade. It's the default with 17.10 fresh install but I don't know what would happen with upgrade. PS2 mode doesn't support as many features as I2C does. If you still aren't happy with the performance in I2C mode you should be able to adjust many options in libinput that can better improve it than switching to PS2 mode offered.

The touchpad works under the BIOS, so I believe that it is not a hardware issue, but a Linux kernel bug. The touchpad does not show up in cat /proc/bus/input/devices For the touchpad, the Vendor name is COMPAL and the Vendor Part Number is PK09000FS0L The problem is currently visible in 4.13.0-16-generic though this kernel originally worked, I believe, and 4.13.0-17 failed. I continued to use 16 for a while, but after the upgrade to 4.13.0-19, 4.13.0-16 stopped working as well.
