I dont really think this is a calibration issue, I think it is some sort of a driver issue or something? I noticed that the usbtouchscreen module is not loaded at boot, so the kernel must be hooking it with the hid? module? I will try jaunty if that would help? and do I need something from teh ubuntu- mobile? Mike -- Michael W.
