I use Ubuntu 12.10 and the touchscreen works almost correctly. The only problem is that in Gtk3 programs you can, if X knows you have a touchscreen, use kinetic scrolling. I can't do this because X detects it as a mouse.
So my question is how do I make X know that the "mouse" is in fact a touchscreen? The touchscreen is an usb:
