I'm not quite clear what you mean here. The behaviour of "0" isn't well defined for the ACPI backlight driver - it's perfectly reasonable for it to turn the backlight off entirely. Anything assuming that "0" is still visible is broken. -- Matthew Garrett | mj...@srcf.ucam.org -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
