All laptops that I have use touchpads that work in absolute mode (Synaptics or ALPS) and they work fairly well. The Synaptics X driver understands the difference in tablet vs. touchpad and does the right thing for touchpads. You just need to make sure that X actually uses Synaptics (xf86-input- synaptics) with your device, emitting BTN_TOOL_FINGER should help a lot. -- 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
