New Radeon 6800 xt Graphics Card, won't boot to desktop only show black screen

So I got a new 2nd graphics card for my PC, and when I turn on my PC it won’t boot to the desktop, it only shows a black screen. It dose work, it boots all the way to the kernal boot screen. But it won’t get past it I don’t know if its a driver issue or what. If I can get help on this that would be great.

P.S 1st card is a Nvidia rtx 2060

I had a similar issue with a new Radeon 6700 XT few days ago. My problem was that I used an old linux kernel (5.10) which would no longer autoupdate since the package linux-latest was abandoned.

You will need linux kernel 5.12 or newer to use your radeon card.
You can switch to a terminal via pressing alt + ctrl + F2 , login and check via uname -a which kernel you are using.

If you are using an old kernel u can update via
sudo mhwd-kernel -i linux512

Please post the output of inxi -SMGazy. But my guess would be that this configuration is not really supported or the Xorg configuration is causing problems. The configs are generally in /etc/X11/ or in the mhwd.d or xorg.conf.d folders therein.
I’m confused though what the point is of having both cards in the system.

There seems to be a timing issue with newer kernels and AMD video cards. You need to set amdgpu in early KMS. The following worked for me on 2 PCs.

sudo nano /etc/mkinitcpio.conf

Find the line that reads MODULES=() and change it to MODULES=(amdgpu)

Then press ctrl + x then press Y

Next sudo mkinitcpio -P to regenerate the initramfs.

Reboot and tell us if that works for you.

Not sure if mixing a Nvidia and an AMD card in one system is a wise thing to do. Maybe you can make it work, I don’t know, but maybe mixing two different vendors’ cards just won’t work.

So I used the uname -a command and I am using the 5.11.18-1 kernel. As for the system output, thus is what its hasUploading: 20210513_170432.jpg…

I used the kernel install command but it is still showing a black screen.

Filled in the modules section with amdgpu, and regenerated the initramfs but no luck. Still shows black screen

Try switching to 5.12 kernel from Manjaro settings manager.
