    Exclamation TOUCH SCREEN resolution

    Hello. I think it's easy question but I can't find easy unswer.
    I have laptop with kubuntu 12.10 and 1280*720 native resolution. Connected it to external HD monitor 1920*1280 resolution and IR touchscreen from WiViTouch.
    dmesg output:

    Using screen settings I've shut down internal laptop LVDS monitor and use only external one. Touchscreen works ok in 1280*720 resolution. If I try to work in Full HD it's not good at all and can't be calibrated by xinput-calibration utility.

    If I press text in the centre of the screen pointer is 10 cm down from actual touch. Only on top it's in the same position.
    Can I fix it somehow? There no xorg.conf in my system even to look there. Please help!

    Thumbs up Solved

    I don't know why but next time I changed screen resolution to 1920*1280 it's somehow fixed itself ^)
