What I haven't seen mentioned thus far and is AFAIUI essential, is the following line in /boot[/firmware/]/config.txt: dtoverlay=vc4-kms-v3d Note that it is not the -fkms- variant and this is not a typo on my end. Cheers, Diederik

Isn't that for the Raspberry Pi Foundation kernel, not the vanilla one? Lucas

IIRC, it was 'pelwell' that said it, so it's certainly for the RPF kernel. I know there are differences between the RPF kernel and the vanilla one, but I didn't know (and would be surprised) if that would entail not using that overlay. I can (ofc) be wrong. I guess it is worth verifying.
