It's not fancy accelerated graphics, but it does work. I mostly have been using newer kernels from buster-backports/sid/experimental, but the buster generation of kernels worked fine for me last I tried. Maybe you have some customization in /etc/X11/xorg.conf* that's telling it to use fbturbo instead of fbdev? What version of u-boot are you running? Again, it's been a while since I tested the version in buster, but I've been using all the versions uploaded since. Mainline (and Debian packaged) u-boot properly configures the framebuffer for quite some releases... Good luck! live well, vagrant
