where are some traces of proprietary nvidia drivers in Johannes's
message ("kernel non-free: series: 340.xx").

That language is simply stating which proprietary (non-free) kernel driver is/was
applicable to his particular GPU.

My bad. Thanks for explanation. I should look closer at inxi. Usually I notice it with "do not use packaged version" preface, that is the reason why I am avoiding it.

Maybe proprietary drivers were not completely removed.

It seems, a part of communication was off-list. Has it been confirmed that there are no complains related to missed firmware files in output of the following command?

    sudo journalctl -b

There is a chance that booting with the display port adapter disconnected, starting

    sudo journalctl -f

and connecting the adapter might be "less noisy".

Firmware packages might be changed between bookworm and trixie. File search is available on https://packages.debian.org

I took note, and have no idea whether working 340 drivers ever
even existed for Bookworm. He may have had no other choice but pure FOSS.

I have no idea what drivers and firmware are used for this hardware in bookworm.

Several years ago I had a custom dkms package for legacy nvidia drivers to use it with newer kernel (unrelated to Apple hardware though). I found an extra patch on some forum. That driver, already unsupported by the vendor, worked a bit better than nouveau. I have not idea if somebody still have patches to make drivers compatible with current kernel API or it is impossible any more.

Is it possible to inspect Debian 12 bookworm configuration using a live
media and try to replicate it for currently installed trixie?
