I think this is related to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1883905.
I have tried the solutions posted on that bug and at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1899258

I tried modifying GRUB_CMDLINE_LINUX_DEFAULT for adding several options such as i8042.nopnp=1
i8042.notimeout
i8042.reset
pci=nocrs
etc..

When using windows, the touchpad is recognized as ELAN0733. I am using a brand new HP ProBook 440 G8.
