The ubuntu certification for this netbook does not mention that the touch-screen is unsupported in Ubuntu 12.04
Initially I had Ubuntu 11.10 installed on this netbook, the touch-screen worked without issue. Upgrading to 12.04, however, has rendered the touch-screen useless. The touch-screen itself is an Ideacom IDC 6651. I've had no luck so far in locating proprietary drivers.
lsusb lists all my other devices correctly, apart from the touchscreen, which is displayed as such:
Bus 004 Device 002: ID 1cb6:6651
xinput does not list it directly, but I believe it to be the Virtual Core XTEST pointer, shown below.
Virtual core pointer id=2 [master pointer (3)]
↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
↳ SynPS/2 Synaptics TouchPad id=11 [slave pointer (2)]
