TBH I was so frustrated with the RPi4 and wasn't sure what needs to be
done I haven't spent *much* time with this.
The only thing I did was to change in config.txt from "vc4-kms-v3d" to
"vc4-fkms-v3d" and rebuilt the image... and it apparently did not help.

Is there something else what needs to be done in .config?
