All I'm trying to say is that the XFree86 project and the DRI projects=20 have already solved the problem of providing reasonable access to 2D=20 and 3D graphics hardware. There isn't much point in pursuing another=20 solution that doesn't leverage that work. --=20 Doug Rabson=09=09=09=09Mail: dfr@nlsystems.com =09=09=09=09=09Phone: +44 20 8348 6160 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
