Ludovic, thanks for the feedback. The Z590 chipset is new (March
2021), but I did see that someone had installed linux on it and so
assumed it could be done. I don't see Gigabyte's specification of the
video chip.

The lspci command returns

  VGA compatible controller: Intel ... Device 4c8a (rev 04)
    (prog-if 00 [VGA controller])

Someone running ubuntu lacked video and had luck by installing the
5.10.0-1019-oem kernel and updating some drivers to testing. But that
was no screen at all, and others don't report the problem.

The non-free and contrib were already specified in my sources.list. I had
not installed firmware-linux but doing so made no diference.

They were both already installed.

You imply it would do me no good to get and install a video card.
That came as a surprise. I had assumed that it was the card is that
made the dpi modes accessible.
