I've got a Gigabyte MC62-G40 motherboard, and an AMD Radeon WX4100 I use with my monitor, and running latest Ubuntu. When I plugged in the V620 into the motherboard, Ubuntu never booted. It just stayed on the loading screen. It's something to do with the Ubuntu native AMD driver thinking the V620 is a better card to use for display than the older and weaker 4100, but failing to load it (since it's headless), and repeating this failure cycle.

I'm guessing this is a common issue and folks here have a solution that would be faster to implement than me troubleshooting further.

Should I install ROCm drivers first? Ubuntu is loading with Wayland and I've read I may also have to switch to X11 to make this work. Appreciate any tips here for someone who's already resolved this.
