This example uses the touchscreen that comes with i.MX51 EVK's parallel LCD

 

Download xserver-xorg-input-evtouch (xserver-xorg-input-evtouch_0.8.8-3build1_armel.deb) from https://launchpad.net/ubuntu/lucid/armel/xserver-xorg-input-evtouch/0.8.8-3build1

 

On i.MX51 EVK board, run “sudo dpkg –i xserver-xorg-input-evtouch_0.8.8-3build1_armel.deb” to install debian package.

Remove evdev config file:

sudo rm /usr/lib/X11/xorg.conf.d/05-evdev.conf 

Change the content of 10-evtouch.conf to:

sudo vi /usr/lib/X11/xorg.conf.d/10-evtouch.conf 
Section "InputClass" 
           Identifier "touchscreen catchall" 
           MatchIsTouchscreen "on" 
           Driver "evtouch" 
           Option "SwapY" "1"

           Option "MinY" "46"

  The MinX, MinY, MaxX and MaxY values can be changed to match the exact configuration of your touchscreen
