[Solved] No output with R5 230 in HPe ML10 server

To free up memory in my home server, I've installed a super cheap R5 230 AMD/ATI PCIe videocard. However, I am unable to get any display, not even during boot. The system continues to use the built in DVI port during boot.

Arch however does detect the hardware installed:

The BIOS/UEFI setup has several options, from choosing DVI port to memory usage for the iGFX and whether or not to scan for an external card. I can also disable the iGFX alltogher, which is my goal.

Now, I don't really care if the BIOS/POST is not displaying, as long as Arch outputs after its booted, its good enough.

Is there anything I need to install for console mode to work (I was under the impression that wasn't necessary) or maybe some kernel parameters?

Even with the internal graphics, I need to use nomodeset parameter otherwise the display goes black.I don't care. I just want a display.

I can ssh into the machine after boot, so even if I have no display, if its booted up I can ssh into it and troubleshoot.

I hope I can get this to work, I want that 1GB memory back for server use .

Thanks!

Solved it by adding amdgpu to the MODULES line and rebuilding initramfs images.
