AMD Radeon Navi GPU

Good question anyone tested without IGPU?
or on X299/X99 motherboard ....
For info a RADEON VII on X299 motherboard has H264/H265 hardware acceleration enable.

I've got the Sapphire Nitro+, removed WEG, disabled iGPU, and I got it going. BUT I seem to be able to only use the 2 HDMI ports on my card. Going DP out from the card to DP in on the monitor seems to produce a black screen.

UPDATE: got the DP working with WEG installed with boot argument agdpmod=pikera added. However, not I have obnoxious red lines/artifacting on desktop. May need to wait for an update to WEG

UPDATE 2: Interesting...the red lines only appear when I am using the Catalina or Mojave dynamic wallpapers, OR any of the still wallpapers that make up the Catalina and Mojave dynamic wallpapers...the Solar Gradients dynamic wallpaper and any other stills dont display any red lines/artifacts...weird.

Strangely, I didn't have WhateverGreen installed anyway and so didn't have to remove it. Disabled iGPU in the bios (was previously set to "Auto") and then tried to boot...

Black screen of sadness :(

Maybe you still have something in your Clover config to make the iGPU to work properly?
 
I can VNC into the box and see that it's recognised, but it's not currently giving me any output to either of the attached monitors (one on Display Port and one on HDMI), I'll keep experimenting...
