The upstream version covers all four edges with AreaLeftEdge and friends. recent X servers also support a percentage as option, so instead of the hardcoded value for the edge, you can say Option "AreaBottomEdge" "20%" I've had a few attempts to fix this touchpad to work slighlty better but the box died on me before I could finish it. Feel free to send me one of these machines if you want it fixed, it's been bugging me for ages :) Cheers, Peter -- 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/
