X is displaying everything it's being fed beautifully with no help. I have to renice Gforce (amarok_libvisual), but given it's very heavy CPU usage, that seems perfectly fine. No regressions noticed so far. Box is _very_ responsive under load, seemingly even more so than with previous releases. That is purely subjective, but the first impression was very distinct. -Mike - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
