Touch Screen 7" PORTRAIT

Hi all,

I would like to use the UDOO board with the proposed 7" touch screen in PORTRAIT mode.

I choose the UBUNTU 12.0.4 LTS distribution but if I solve this problem on other distribution (like Debian) i can change. The following development are made on UBUNTU.

I order to rotate the screen I change the Device Driver from "vivante" to "fbdev" in "xorg.conf " file. I this way the system take into account the rotation options. E.g.

Code:

        
Section "Device"
        Identifier      "i.MX Accelerated Framebuffer Device"
        Driver             "fbdev" #"vivante"
        Option          "RandRRotation" "on"
        Option          "Rotate" "CCW"
        Option          "fbdev"         "/dev/fb0"
        Option          "vivante_fbdev" "/dev/fb0"
        Option          "HWcursor"      "false"
EndSection

So Now I can not rotate the touch input. I know I have to change the 99-calibration.conf file like this:

Code:

Section "InputClass"
       Identifier "calibration"
       MatchProduct "sitronix-i2c-touch-mt"
       Option  "Calibration"   "797 49 474 18"
       Option  "SwapAxes"      "1"
       Option "InvertX" "0"
       Option "InvertY" "0"
EndSection

... and, of course, the "xinput_calibrator" command can help me.

But does not works. The feedback pointer on screen is still in wrong position and direction.
I think this message in "Xorg.0.log " can help us:

Code:

[    59.560] (**) sitronix-i2c-touch-mt: Applying InputClass "calibration"
[    59.560] (II) No input driver specified, ignoring this device.
[    59.560] (II) This device may have been added with another device file.

Seems to need a driver... I do not know.

Thanks in advance to all give me a solution right or wrong... bye
