Hi! I am not sure this is the correct group to be asking this
question, but here I go anyway:

I am interested in incorporating graphics capabilities into my MINIX
kernel (MINIX is a UNIX feel-alike OS which runs on personal
computers). To that effect, I was wondering how are graphics done (at
the lowest level) on unix boxes, like the sun workstations, for
instance. That is, I would like to know how are the screen drivers
implemented. Is the screen just a normal special device to which one
(or root) can write to produce the bitmap, or are there special system
calls to do the plotting, or how is it done? I would appreciate if you
could mail me any info you have on this subject, or pointers to where
such info can be found. Thanks a lot!
