That's a separate graphics card, isn't it? I'm trying to use the
integrated graphics processor on my Ryzen 7900.

When I do lspci | grep -i vga, I just get:
VGA compatible controller, Advanced Micro Devices, Inc [AMD/ATI] Raphael
(rev c4),
(well, something very similar, I'm copying it by hand). The "Raphael",
I believe, is the codename for the entire 7900 processor, not just the
graphics controller.

As I reported in another post, dmesg | grep firmware just gives me three
files, none of them to do with graphics.

Yes, I get something like that on the installation system.
