Ok, now it looks like you're running into the next issue. Kernel >= 5.10 is mandatory for the driver!
https://community.amd.com/t5/graphics/rx...d-p/446872
Which UBUNTU version have you tried?
$ uname -r

I'm running Arch Linux and kernel 5.11.6
In may case, uname will show this:

Code:

$ uname -r
5.11.6-arch1-1

"I am wondering if this is purely a RADEON thing?"
I don't use AMD, because, according to this:
https://rocmdocs.amd.com/en/latest/Insta...Guide.html
only 3 distributions (and only limited versions/kernels of this distributions) are official supported by rocm:

Code:

Ubuntu 20.04.1 (5.4 and 5.6-oem) and 18.04.5 (Kernel 5.4)
CentOS 7.9 (3.10.0-1127) & RHEL 7.9 (3.10.0-1160.6.1.el7) (Using devtoolset-7 runtime support)
CentOS 8.3 (4.18.0-193.el8) and RHEL 8.3 (4.18.0-193.1.1.el8) (devtoolset is not required)
SLES 15 SP2

I believe, Linux is more than this...

Prefering Arch Linux as distribution, that made my decision easier:

Code:

$ lscpu
Modellname: AMD Ryzen 7 1700 Eight-Core Processor

$ lspci
26:00.0 VGA compatible controller: NVIDIA Corporation GP102 [GeForce GTX 1080 Ti] (rev a1)

Absolutely no problems here, running this combination.
