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
