Certainly you need a driver that supports multitouch, but it's not just a driver issue. There are multiple versions of synaptics hardware ranging from: * single touch only * multi-finger (one coordinate, but tells you number of fingers on pad) * semi-multitouch (bounding box of two touches, you don't know which :) * limited full multitouch (tells up to 3 locations, up to 5 touches in total, you don't know which touches you get locations for :) * full multitouch up to 10 touches (I've heard of this latest gen, have yet to see one in person, I don't think there's any linux support yet) You can imagine how much fun it has been to figure this all out... -- Chase _______________________________________________ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list
