Comments/Problems:
Am not sure if os-prober ran, it didn't detect a Windows install on another drive. Other bootloader was not damaged and UEFI entries seem correct.

I am currently in a terminal because upon logging in I immediately got graphical corruption including quite rapid flashing on the desktop.
I know, NVidia card, but at least boot to a safe graphics mode and let me install a different driver.

The prompting to install firmware for sound (?) was a bit odd but did not impact the rest of the install.

Haven't tested my PCIe sound card yet due to the graphical issues.

Please make sure that any installation logs that you think would
be useful are attached to this report. (You can find them in the
installer system in /var/log/ and later on the installed system
under /var/log/installer.) Please compress large files using gzip.

Hello Adam,

I've seen some issues on openQA which run on AMD hardware, but I
personally only have Intel processors, so I cannot reproduce such
issues. [1]

Can you confirm that the microcode is active?
sudo journalctl --boot | grep microcode

Could you try uninstalling the package 'amd-microcode'?
sudo apt-get remove amd-microcode
sudo update-initramfs -u

Does that fix your graphical issues?

With kind regards,
Roland Clobus

It was, but I forgot to capture this output.

No, but installing the non-free nvidia-driver did. It's a pity, as I don't need anything nouveau couldn't theoretically provide.

Thanks anyway.
