Hi!

I have a new home server with efi bios and want to use my old 14" VGA
monitor (AOC cmlb-335).

How to setup grub2 to use 640x480 or 800x600 with 60-70Hz? GRUB_GFXMODE="640x480x16" does not work well. Screen is not readable
then, seems to be out of range.

Grapics is buildin Ryzen 5 4600G.

What does the firmware have to do with if VGA works or not?

That's a graphics configuration problem.

Try text mode without graphics.

I would sincerely hope that it still supports the venerable VGA text modes.

Because UEFI killed VGA VESA.

Thank you for explaining. I was not aware of that.
