So recently, I bought a Lenovo Ideapad z400, which has a wonderful 10-point multi-touch screen. I absolutely hate Windows 8, so I decided to try to dual boot Ubuntu. I did the installation after the trial worked perfectly with the touchscreen. But ever since, the touch screen is not recognized by Ubuntu-or so it seems. (It still works on windows 8.) I honestly have no idea what I'm doing, as this is my first time ever using any Linux OS, as well as a touchscreen laptop. Anyone able to help or have any thoughts on this?
