NVIDIA and AMD Driver Conflict on Arch Linux

I have 2 GPUs installed in my computer. RX 6600, installed in a gen 3 PCIe x16 slot, and GTX 960 installed via an NVME to PCIe riser cable. Xorg will not start, and after playing with the Xorg configuration file with any success, I tried using hashcat -b to run a benchmark, but it threw the same error for every hash type.

Relevant info: https://pastebin.com/m8TVx8YX

Let me know if there's any more info that could help diagnose the problem. Also, this is my first post to the Arch Forums, so I'm sorry if this is not the correct topic to post under. I usually take a long time to respond and I apologize in advance.

Re: NVIDIA and AMD Driver Conflict on Arch Linux

first: delete the xorg.conf - it likely causes more harm and is it not required - a modern system should work fine without it
second: remove the additional kernel parameters - i don't know if amdgpu.modeset=1 is a thing but if it likely conflicts with nvidia-drm.modeset=1
third: if you have modified your mkinitcpio.conf - like did the alterations mentioned in the wiki nvidia article - revert it to normal - from your post the nvid card is not your primary gpu (and i doubt the uefi recognize it as such when plugged in a slot meant for storage)
have you tried to plug the nvid card into a regular pci-e slot just for the sake to check wether it even works? have you tested tge nvid card on its own?

Deleting xorg.conf was the answer. Thanks!
