To get support for our latest graphics cards (Radeon RX 6x00 series), here are the components that you will need:

Kernel 5.10 or newer
Mesa 20.2 (or optionally, Oibaf mesa 21.0 from here: https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers)
llvm 11.0 or newer

Well I updated my kernel Linux 5.10.12-051012-generic x86_64 GNU/Linux

I tried to install LLVM by

1. adding this APT to the software update control panel deb http://apt.llvm.org/focal/ llvm-toolchain-focal-11 main
2. adding the gpg key sudo wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key|sudo apt-key add -
3. updating the cache sudo apt-get update
4. installed clang, etc with sudo apt-get install clang-11 clang-tools-11 clang-11-doc libclang-common-11-dev libclang-11-dev libclang1-11 clang-format-11 python-clang-11 clangd-11 lldb-11 lld-11
5. got this error E: Unable to locate package python-clang-11
6. checked my version of clang clang --version clang version 10.0.0-4ubuntu1 Target: x86_64-pc-linux-gnu Thread model: posix InstalledDir: /usr/bin
7. checked my version of LLVM llvm-config --version 10.0.0

I dont know why I am at version 10 for clang and LLVM? I havent got a clue how to install MESA.

So I just downloaded the drivers and did this in a terminal:

./amdgpu-install -y

during the install I saw this:

Building initial module for 5.10.12-051012-generic
ERROR (dkms apport): kernel package linux-headers-5.10.12-051012-generic is not
supported

so I had to uninstall the drivers and then do this:

sudo ./amdgpu-install --no-dkms

Instead of 810 MB install there was 566 MB . What is dkms and do I need it?

Anyway, it did not work.
