I found a workaround which should make the touchpad work in ps/2 mouse emulation mode.

You need to add a Kernel Boot Parameter to set the flag i8042.nomux=1 psmouse.proto=bare which will enable PS/2 Mouse Emulation mode on your touchpad.
Edit your default grub file.
sudo nano /etc/default/grub
Find the line that mentions GRUB_CMDLINE_LINUX and add the flag:
GRUB_CMDLINE_LINUX="i8042.noloop=1 psmouse.proto=bare"
Then save the file and run a grub update.
sudo grub-update
Then restart the system .
