[comp.unix.aux] Graphics accelerators under A/UX for 19" displays ?

lamarche@ireq.hydro.qc.ca (06/05/90)

I am considering to get a 19" display for my mac II to operate with  X11R4.
Does any body have any experience with Supermac or Radius displays? Does
the use of graphic accelerator improves performance in this situation?

No graphics accellerator, as far as I know right now, is supported
by A/UX 2.0.  That includes the 8/24 GC.  The problem as it's been
explained to me is that existing accellerator code assumes a
physical==virtual identity for the cards' bitmaps, which is no longer
true under A/UX.

There's no 24-bit support in the Apple X11R4 anyway, just 1-bit and 8-bit.
