Thanks for your comments, but it seems the MSI Gaming X series is not a 
reference card (its factory overclocked).

I dont think this is the case here, as using GPU-Z under Windows shows a 
valid EFI rom. It seems a Linux issue only, I have submitted a case with 
MSI to see what they say.

Thanks, if I add the rom (the one I saved using GPU-Z under Windows) my 
display turns on.

Unfortunately it didnt work then yet, as my dmesg was flooded with the 
following message:
vfio-pci 0000:01:00.0: BAR 0: can't reserve [mem 0xc0000000-0xcfffffff 
64bit pref]

This was caused due grub loading vesafb for the RX480 as the graphical 
terminal was enabled. So in /etc/default/grub I had to add 
GRUB_GFXPAYLOAD_LINUX="text" and disable 'GRUB_GFXMODE' (not sure about 
the last one as maybe thats implicit but it doesnt hurt either).

Unfortunately that does mean I cant use ddccontrol it seems, as that 
complains about missing a framebuffer driver. Therefore I've also asked 
Asus whether they plan to support choosing the primary vga slot like 
Gigabyte does and they said 'they will discuss this internally'.
My Asus support agent actually had never heard of vfio before and 
repeatedly said that Asus only supports multiple GPU's when using 
SLI/Crossfire. So maybe if more people would contact their local Asus 
support agent and request this feature they are more willing to look at 
it? Who takes the hint? ;)

I had to install the driver twice as the first time the install failed, 
but at the moment the GPU appears to be working correctly. Now first on 
to sound before I do some 3D testing.

Kind rgds, Pim
