[amdgpu] Video does not output to second monitor

[Drew Howden]

I have a 2-display setup (laptop screen with second monitor). When I am booted into Linux kernel 6.5.0-14-generic, my laptop screen works fine, however my second monitor doesn't get any video input at all.

This problem does not occur on previous Linux kernel versions.
