Thanks to @kkert’s Debian buster image. It is interesting! I have tried it on VIM2.
But the HDMI display is blank with the message in kernel log:

There used to be a time for me on gentoo when (kernel,Xorg,mesa) version triplet got confused about 2 /dev/dri cards (card0 and card1), and in particular: Xorg would fail.
If I renamed card0 to, say _card0, I would end up running Xorg with Panfrost, if I renamed card1 to, say _card1, I would end up running Xorg with framebuffer (or maybe it was vice versa).
