Hello,
It seems that this touchpad is a bit temperamental; have you tried what is explained in this discussion?
You can modify kernel parameters through grub (via the advanced options). If it works, to make these changes persistent, you need to edit/etc/default/grub
by running the following command from a terminal:
pkexec gedit /etc/default/grub &
In your editor, modify the line:
GRUB_CMDLINE_LINUX=""
... to:
GRUB_CMDLINE_LINUX="i8042.nopnp=1 pci=nocrs"
Finally, you need to propagate this change by running the command in a terminal:
sudo update-grub
Good luck!
