I use the MX Linux distribution (Debian-based) as my dual-boot. Recently, I've started building a new PC, the crux of which will be a Radeon RX 7900xtx GPU. Since it showed up before everything else, I crammed it into my current PC to replace a GTX970 to test and play around.

After some fun with the Dell BIOS not giving me any video out, I got it running great in Windows. However, when booting into MX Linux, the system simply hangs on a flashing cursor forever. If I press the power button, it shows the normal shutdown text of stopping services and shuts down fine, so I know it's not a hard crash, just a silent hang.

I'm assuming this is related to the NVidia drivers being embedded in the kernel or something and it just can't figure out how to initialize the Radeon card? I was using the NVidia proprietary drivers on my GTX970 before, installed through the MX Linux repos.

Any advice or guides you might have to get this install working again would be great! It would be no great loss if I had to reinstall it since I'll be moving to a totally new PC anyway, but I'd like to try and save this install anyway.
