Oh, but when I run the XFCE image (with ext4 /boot as shipped) and
remove /boot/dtb... X just errors out with "no screens found". So I
can't do that either, unless there's something to change in config.txt
to match (or at least be close enough) to the kernel-provided device
tree.
All the bits for screen enablement using upstream drivers should be
there by default. What else have you done to your config.txt? What
exactly is the revision of RPi?
