After following these steps, and with the latest image from https://cdimage.debian.org/cdimage/ports/snapshots/2022-03-28/ which installs fine btw, the screen stays blank. Adding nomodeset to Grub enables me to boot to a login screen, but then after installing a desktop environment startx will fail with an error related to nomodeset. (it did in my previous install, I haven't tried to install a graphical environment this time.) Peter > > Adrian >
