I have the same issue on a sony vaio duo 11 with ubuntu 13.04 and kernel http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-rc8-raring/ . (Kernels earlier than 3.9 do not properly support duo's N-Trig DuoSense Touch Screen - see https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/1121379 ).
