I also was having some weird calibration problems with two mice, but that might’ve just been a fluke. A modeline is a configuration line in a configuration file that provides information to the server about a connected computer monitor and how to drive it at a specified display resolution. My suggestion is download another program from http: If your touchscreen has an USB interface, and it isn’t working, then you may need to blacklist the usbtouchscreen driver for it to work: The touchscreen is for input only; therefore, you need something behind it to display an image.
