I received my two 7" Touchscreen display units yesterday and hooked them up as instructed. The screen works wonderfully, but I cannot get touch inputs to register. I'm sure there must be a driver I need to load, or a program I should run to try to test, but so far firing up a Kivy demonstration did not register the touch events so I'm concerned my first-run units are faulty.

I am on the latest copy of raspbian (via apt-get upgrade) but my bootloader is likely from May.

What is needed to properly test the official 7" Touchscreen?

    It probably won't do any harm to do a sudo rpi-update to ensure you have the latest version of firmware. I wouldn't have thought it would be necessary if you have done a update/upgrade, but who knows. – joan Sep 16 '15 at 13:23
  • Ah hah! I updated the firmware and it worked as expected. It would be nice to know if there's a particular kernel module or test tool to ensure it is working with all ten touch inputs, though. – Peter Grace Sep 16 '15 at 13:31
  • Can not help with that, do not have the device. I do not remember seeing anything about a test suite though. – joan Sep 16 '15 at 13:41

TMWILSON 26 referred me to this link. It's a 'custom driver' which works with a lot of touch screens. This got the touch screen working for me in X, not in Kivy yet.

Hope this helps.
