I'm trying to calibrate touchscreen on Ubuntu 12.04. My monitor is NEC MultiSync LCD225WXM and second display device is HD TV there are connect to Nvidia cart with TwinView enabled (I must set TwinView from other reasons). The Resolution is 1680x1050 NEC LCD and HD TV 1366x768. I create software to (display movies and presentation on HD TV etc...) and control panel is on Monitor LCD.

My problem is that i can`t set correctly touchscreen when I connect HD TV.

Where is use only LCD Monitor there is no problem xinput_calibration work perfect but where I connect HD TV there is impossible to use xinput_calibration (because is TwinView)

Can any one help me:

  1. Is there possibility to correctly calculate good parameters for xinput:

This was perfect only for one LCD monitor:

xinput set-int-prop "eGalax Inc. USB TouchController" "Evdev Axis Calibration" 32 75 1995 114 1884
