I have recently purchased a cx210x gateway tablet laptop and it came with ubuntu, which I am very fond of now that I have had the chance to use it. However the touchscreen that only works with the stylus gives me a message that there are no calibratable devices found. I ordered a new stylus which I received today and it is still giving me the same message on the calibrate touchscreen window. A little help if you please, this is very discouraging and I am close to just wiping and re-installing windows.
