NVIDIA Driver 410.78 causing login loop


I am currently experiencing an issue with a login loop that I have narrowed down to being cause by the installation of NVIDIA Driver 410.78, I am working on Linux Ubuntu 16.04 Xenial.

I have tried multiple troubleshoots from previous postings about older driver versions.
Some of which are: $ sudo mv ~/.config/dconf/user ~/.config/dconf/user.old

and $sudo mv ~/.Xauthority ~/.Xauthority.backup
$sudo service lightdm restart

but they have not helped solve the problem. I end up having to uninstall the driver to login to my system and then reinstall the driver to use it. Then if the system were to be rebooted, the issue happens all over again and I have to repeat the process.

Any help to remedy this issue would be much appreciated. Thank you.

I have attached the nivia-bug-report to my previous posting. Thanks.

You are using the onboard AST video, not the nvidia, is that intentional?
If so, create a file /etc/X11/xorg.conf containing

Section "Device"
    Identifier     "AST"
    Driver         "modesetting"
    BusID          "PCI:5:0:0"
    ModulePath     "/usr/lib/xorg/modules"

and add the kernel parameter


and see if that helps.
