Bug#939401: nvidia-driver: Xorg crashing in an endless loop after upgrade to version 430

[Niklas Schmidt]

Package: nvidia-driver
Version: 430.40-2
Severity: grave
Justification: renders package unusable

Dear Maintainer,

   * What led up to the situation?
      I upgraded the nvidia-driver package (version 418) to the newer version 430.40-2   

   * What was the outcome of this action?      
      Every time I boot my computer with the NVIDIA driver version 430 installed, I end up in an infinite loop between the tty and Xorg starting and instantly crashing. Switching ttys does not seem to work.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?   
      I tried rebooting with an older kernel to reinstall the driver, which did not work. I also tried unplugging my second monitor and deleting the xorg.conf file. This didn't help either. I have resorted to using the legacy 390 driver for now.
   
   * What outcome did you expect instead?
      I expected my system to boot normally after the upgrade.   

   I use a GTX 1050 Ti with a dual-monitor setup, one monitor using DVI and one using HDMI. The Xorg log can be found here: https://paste.debian.net/1098761/
