I don't know of anyone working on it. It was always a distant TODO when we were first doing the KMS work, and it's theoretically possible to have VGA text & graphics modes available as part of KMS, but it would require some big additions to the graphics drivers. VGA modes tend to take a lot more power than high res modes too, since they activate power hungry legacy hardware that is otherwise disabled. > Also, having it essentially necessary for some environments > (co-existing with Xserver-xorg-radion) and unusable with others, such > as VESA in VM is not a very good situation. Why not? Machines typically have supported devices or not; if so they can use all the good stuff, if not, they can use the compatibility code (like VESA) exclusively. -- Jesse Barnes, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
