I have xinput test 8 to see touch screen inputs. But since 5 hours i can not see where its touching. Before 5 hours it was working fine.

Then i updated the kernel and also updated to latest kernel but the problem remain same as always. How can i make sure the xinput test 8 capture of touchscreen is working at all or not?

It's not entirely clear from your question whether your touch screen completely stopped working, or that it's just xinput test that stopped working.

In the latter case: It is possible that the device id 8 has changed. Try running

xinput list

and see what id number it says next to your touch screen. Then substitute it like

xinput test NUMBER

Its working with old kernel, latest all kernels does not work and its slow when touch is pressed.

$ sudo modprobe elo`
$ uname -r 
3.2.0-29-generic
