Try: InputDevice "<device>" "SendCoreEvents" instead of InputDevice "<device>" "CorePointer" I got my laptop set up with one CorePointer and one SendCoreEvents, if i inplugg my SendCoreEvents device, X starts just fine :) Svein Erik >>> ARokicki@xxxxxxxxxxxxx 17/09 2:22 >>> I have industrial robotic application that I need to run touch screen OR/AND a mouse. Machines will have mouse or touch screen or both or no pointer. X works fine as long as mouse and touch screen is plugged in. If only touch screen is plugged in X locks up the screen. I have googled for a while now with not usable results. Thanks Andy R.
