As I mentioned before, K A L I is doing it's own configuration and "/etc/X11/xorg.conf.d/" is empty on your system.
I assume K A L I let Xorg autoconfigure and/or the config file is this: "/etc/X11/xorg.conf"
Also you should figure out, what driver is installed/used by K A L I.

Setting kernel parameters is explained here:
https://wiki.archlinux.org/index.php/Kernel_parameters
It highly depend on your system. I assume, K A L I is running GRUB.
BTW:
Most tips and tricks from the Arch wiki will work on every Linux system. It is one of the best wiki's I have ever seen.

"During the nomodeset boot it comes up with a bunch of stuff to do with amd and vga errors..."
For sure it will do, because K A L I is not configured for your hardware! The pre-configuration is standard and not useful for you.
Please notice: K A L I is designed to run within a virtual box or on an USB device on most of the hardware.

I also recommend to take a look at the services

Code:

$ sudo systemctl list-units --type=service

Later on, you should disable every service that you don't need.
That will speed up your system.

Ok so I figured out using nano for the grub file like you said and it just said ''quiet'' and not ''quiet splash'' so I just added in ''nomodeset'' after quiet pressed ctrl+o to save then ctrl +x to exit then sudo updtate-grub and then rebooted and it worked and now The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) boots without me having to manually put in nomodeset each time so that is that problem solved for now.

I checked in the repository and the AMD drivers for K A L I are installed. But for some reason i can not find how to use them or check if they are used. When I typed in those commands from before it APPEARS that the system is running off the default AMD display adaptor built into the mobo. The 6900xt showed as there but had no drivers listed. Really not sure where to go at this stage or what to do. AMD does not appear to have Debian supported drivers from what I can see?

Oh and the errors in start up say :

[drm:amdgpu_init [amdgpu]] *ERROR* VGACOM disables amdgpu kernal modesetting.

[sda] No Caching mode page found

[sda] Assuming drive cache: write though

Maybe I set up the disk wrong on the firecuda? Running full disk encryption from The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali).

Again any help you provide is appreciated man I feel we are making progress and getting to the bottom of the problem and getting the puppy up and running to get some good benches and good real world cracks going.
