Help...First time installing a Radeon on Linux (7800 XT) (lemm.ee)

Hi guys! Brand new PC...And I'm trying to install its brand new 7800XT. I've chosen KDE Neon, as it was my previous OS, and I've grown to like it. I'd like to stick with it if possible...I'm writing this preamble, because when I try to run amdgpu-install from the AMD downloads page, all I get is:

Unsupported OS: /etc/os-release ID 'neon'

So...what can I do? Neon is mostly Ubuntu 22.04 to most effects. Kernel is 6.2.0-36-generic.

Thanks!

Sigh...Just for the sake of it...It needed to recompile the kernel with the LATEST firmware you needed to download manually. Instructions here: https://askubuntu.com/questions/1451506/how-to-make-ubuntu-22-04-work-with-a-radeon-rx-7900-xtx

I changed the file download to the latest, which at this moment is linux-firmware-20231111.tar.gz. After the update-initramfs, reboot (since I already ran the PPA earlier...to no avail), and this time it worked, and it immediately showed me the second monitor, which had been dead for the last couple of hours since I started fighting this thing.

A second update after this is, since I'm using Wayland and multi-monitor (two HDMI connections, one the main monitor, the second to a big LCD TV)...when the TV is turned off, the monitor starts to flicker rearranging the windows (!?). I describe the issue a bit more in detail here... https://lemm.ee/post/14853567
