    Hello I recently purchased your LCD "touch product 7 and I configured it with your tutorrial (http://www.udoo.org/ProjectsAndTutorial ... lioID=1394).
    screen works correctly (which is the display) BUT the touch screen will not work. yet I followed the information correctly. I look application calibrate touchscreen and the terminal print : Error: no calibratable devices found. I look again in xinput if it was detected but it is not.

    i use ubuntu 12.04

    Here are the steps that I did:
    -connect screen
    - i connected in de desktop in ssh (serie)
    - enter
    - setenv mmcargs setenv bootargs console=${console},${baudrate} root=${mmcroot} ${hdmi_patch} fbmem=24M video=mxcfb0:dev=ldb,LDB-WVGA,if=RGB666,bpp=32
    - saveenv
    - boot

    after boot the screen is open (but no touch)
    a try to lunch app calibrate touchscreen and Erreur

    a try to edit file in "/etc/X11/xorg.conf.d/99-calibration.conf"


    Section "InputClass"
    Identifier "calibration"
    MatchProduct "3M 3M USB Touchscreen - EX II"
    Option "Calibration" "-75 65106 2318 65008"
    Option "SwapAxes" "0"
    Option "InvertX" "1"
    Option "InvertY" "0"
    EndSection

    i try xinput_calibrator in the terminal and same error

    The lament was up to furnish the post on the front side, I was unfortunately not yet found a solution. I contacted via a ticket udoo and they gave me an answer:
    After this message I tested and no response from the screen (cat / dev / input / eventX (X = 0,1,2,3, ...) so I'm trying to make change, because the price that it cost i want to make it work. it is unfortunate that the answers are EXTREMELY slow ticket

    Just to give an update to this, at the moment 7" and 15" LVDS are fully functional (video and touch) on both the Dual and the Quad using Ubuntu.
    With Android only the 7" with the Quad is fully functional (video and touch).

    The 15" touch is not working on the Dual neither on the Quad while using Android. The next Android release will fix this.
