Description

A user as reported being able to boot with a problematic GPU.

Their setup is as follows:

- Gigabyte AB350N

- AMD Ryzen 5 1600X CPU
- AMD Radeon RX 480 GPU

It’s possible that this workaround could apply to any computer with a Radeon RX, or perhaps the combination Ryzen/Radeon (needs testing)

The user reported this link as a source: https://askubuntu.com/questions/1029517/amd-rx480-screen-flicker-after-update-to-18-04
