However, it would seem at first glance that early
SunOS also had a

to the hardware frame buffer, and ioctl’s to probe and configure the
hardware). Is that correct, or were these entirely different in nature?
My limited understanding is that PC compatibles, and thus Linux, with
their VGA et al. cards had /text/ character support that other systems
did not have. As such PCs ~> Linux /didn't/ /need/ frame buffer support
in the beginning.
Conversely all systems that didn't have such cards /did/ /need/ frame
buffer from the start.
I consider Linux's frame buffer to be a late comer compared to other
systems.
