http://ubuntuforums.org – Hello, we have some Lenovo C200 computers, and we have huge problems with the touchscreen when we install Ubuntu. After we made the setup of Ubuntu on our computers, we switch to the desktop, and then we cant use the touchscreen. Somehow we cant calibrate the touchscreen and when we pressing the touchscreen, the mouse is moving weird around on the screen. My question is, how can we solve this problem? We've also downloaded "Xinput" and tried to calibrate it with it, but also the same problem. However, i hope someone can help us to fix this problem as soon as possible. T (Hardware)
