Well, Ubuntu 18.04 itself was released in April 2018, prior
Debian Buster's freeze period January this year.  Ubuntu 18.04.3
however has been released in April this year, after the freeze,
but before the release of Debian 10:

https://wiki.ubuntu.com/BionicBeaver/ReleaseNotes/ChangeSummary/18.04.3

Since Ubuntu is based on Debian Testing, it might have been
reasonable to expect Debian 10 to be sufficient for your
hardware; but reality seems to have proven otherwise.

Maybe updates regarding driver support and firmware have landed
between each minor updates?  I see a few occurrences to "amdgpu"
in each release notes.  You could have been hit by one these
little missing bits.

Stupid me, not having asked this earlier!  If you happen to
retry Debian one day, and if that still fails, then it would be
interesting to post your "dmesg" output, "Xorg.0.log" content,
and other applicable logged information.

Ubuntu and Debian have differing goals, although both would tend
to be an "Universal Operating System".  The first one tends to
putting GNU/Linux in anyone's hands, while the second would more
emphasize respect of the Free Software spirit, at the expense of
usability, alas, sometimes.

From what I understand, a lot of hard work is done by both
sides, benefiting to both distributions.

Kind Regards,  :)

It was Ubuntu 18.04.3 LTS.

Given that Ubuntu is based on Debian, drawing liberally on their work is not
only shameless, it is a savvy arrangement to avoid doing the same work twice.

Out of curiosity, which Ubuntu release did the job?

It could give a clue as of required firmware or drivers levels
for your integrated card, or any other missing component.

Kind Regards,  :)

For the record, it doesn't work.  I additionally tinkered for a while with the
drivers supplied by AMD, but didn't succeed.  Eventually, I gave up.  Ubuntu
recognizes it out of the box.

Thank you Sven for pointing this out!  You're right, I've been
confused by personal experience with other chips.  Installation
of "firmware-amd-graphics" should be sufficient in that case.
I should probably refrain to post past a certain hour in my TZ.

Anyway, Kind Regards,  :)

Yes, it is used in the Ryzen 2300U mobile processor[1].

No, the 4.20 kernel added support for the brand-new 7nm Vega20 GPUs.
Older Vega GPUs such as Alassandro's are supported in 4.19.

The graphics card actually needs firmware-amd-graphics.  The
amd64-microcode package is for the CPU, and is recommended if the
manufacturer does not provide firmware updates.

AMD Vega 6 on Debian 10 (Was: Is Buster ready?)

Good day,

I don't see your chip in the "AMD Product Family Compatibility",
so that's probably a dead end.  Also the "firmware-amd-graphics"
non-free package does not advertise compatibility with it.  From
what I understand, this is some sort of AMD integrated graphics.

It is possible that your hardware is a wee bit too recent for
Debian 10 vanilla: Vega support for the amdgpu driver landed in
Linux 4.20, but Debian 10 ships with kernel version 4.19.

You will have more chances with Linux 5.2 from buster-backports.
Also there is a faint possibility that your chip might require a
firmware update through the non-free package "amd64-microcode".

Kind Regards,  :)
