It looks SUSE recommends to do so in one of the Wikis.. There certainly lots of recommendations to do so in case of keyboard resume troubles all over the forums (Ubunto, Gentoo, other random ones). > And this patch will > not solve that problem, just forbid it from happening, right? > It will prevent unbind from happening so that users who have suspend and resume working properly but who have bind/unbind in their suspend/resume scripts regardless will not run into trouble. This still leaves users whose suspend/resume don't work by default but I would rather fix their boxes properly instead of relying on that workaround. -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
