[ 17.153191] input: appletouch as /class/input/input9 [ 23.563768] appletouch: incomplete data package (first byte: 2, length: 4). Now keep in mind, from my perspective maybe this is caused by appletouch not properly configured i.g. whenever I was using xorg 7.1 appletouch worked great (two and three finger tap, scroll), but as soon as I loaded xorg 7.3, the only function I have is two finger scroll.(still need to figure out why my xorg.conf is not working with appletouch) So maybe having xorg.conf not proper is resulting in this from above. (but then again could not have anything to do with the above.) regards; -- Justin P.
