I confirm what zob wrote. I switched from Discrete to Hybrid mode in BIOS and now touchpad work fine. I use Nvidia proprietary driver from ubuntu standard repository (440.64), my only problem is screen tearing (PRIME profile set to performance mode). I don't know if the drivers from PPA repository fix touchpad and tearing problem. I read that Nvidia 440.66.11 Linux driver fixes annoying bugs With PRIME Sync: https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-440.66.11-Linux. Previously I used the card in discrete mode with Fedora 31 and the proprietary Nvidia drivers 440.82 from RPM Fusion repository without any problems for touchpad or for tearing.

The same machine has been working fine with ubuntu 16.04 and 18.10. To be more correct it is still working in 16.04 hwe which I'm dual booting. If I uninstall the nvidia drivers (right now 418.56-0ubuntu1), and replace with noveau drivers it works just fine (by the way there seems to be no other issues with the nvidia driver as of yet). I have also the nvidia-driver-390 also suggested in the graphical software updates tool, to no avail. I will attach relevant logs. Please let me know if there is more I should supply. And thanks for all your hard (and brilliant) work.
