Ok, now let’s see if you can switch to nvidia. The v430 driver from ppa already seems to be installed.
Please make sure the package nvidia-prime is installed
sudo apt install nvidia-prime
Try switching to nvidia:
sudo prime-select nvidia
Remove any stray blacklist files:
sudo rm /etc/modprobe.d/blacklist-nvidia.conf /lib/modprobe.d/blacklist-nvidia.conf
Update the initrd:
sudo update-initramfs -u
and reboot. Please create a new nvidia-bug-report.log afterwards.
