Comment 3 for bug 1776044

I have a similar issue. Installed Ubuntu 18.04 on a Ryzen 7 2700x with an old Geforce 8600 GTS. Using the built-in drivers, the video card stalls (took me a long time to figure out it was the video card, after going through all the Ryzen issues). I installed the nvidia-340 as recommended, and the system hangs on boot before the graphic login. I removed the nvidia drivers, and reinstall the default, and it works again, but stalls. I know this is the video stalling, as I can ssh into the machine, and all is working fine on the computer, just the video on the hardware is stalling.
