Problem on touchscreen on IMX53-START-R board

I've a IMX53-START-R board connected ti a MCIMX-LVDS1 board.

The software I'm using is the one provided on the original SD card (the name I think is UBUNTU 11_09 DEMO IMAGE).

I think I've properly configurated the boot (setting the bootargs_base parameter) in order to use a LVDS display; in fact, I see the ubuntu 10.04 desktop and I can use usb mouse and keyboard properly.

 

What I can't use is the touchscreen. If I use the "virgin" SD card, if I touch the screen I see the mouse cursor go to the center of the screen. The procedure for configure the touchscreen doesn't work and seems to be sensible to the mouse pointer and not to the touchscreen.

 

I tried to look to the older post and I've seen a problem similar to mine:

 

imx53qsb with ubuntu 10.04 and MCIMX-LVDS1 touchscreen

 

If I try that procedure but, when I touch the screen, the cursor goes to the upper left corner. What am I doing wrong?

I think the touch screen is "captured" by the system but not properly. Is there something I can do in order to use the touchscreen?

 

Thanks
