    I received my kickstarter pledge and assembled the PiScreen today.

    After connecting to it, I can't seem to display either the test image, or the console on it.

    The backlight works both in hardware and software. I can see the device in /dev/fb1 and /dev/input/event0, as well as /proc/bus/input/devices

    Neither the evtest or ts_bin tests show any form of touch input, even though I can see a mouse in my hardware listing, despite having no USB mice connected

    Can please show me the output of these commands

    dmesg
    ls -l /dev/input/event*
    cat /proc/bus/input/devices

    Hi Mark,

    Here are the outputs you asked for:

    dmesg
    ls
    cat

    Everything in that output looks correct.
    One last question.
    When starting X Windows, Does the touchscreen work with the calibration program that runs just before X Windows?

    The touchscreen shows no images and sends no touch events whatsoever.

    Even after setting it to display the console, and when trying to display the test logo image, I can see nothing on the screen.

    Neither the calibration program, nor evtest can receive any touch events from the screen.

    I have a feeling that the screen unit itself is defective, as even when the backlight is on, I need to push the screen up from its bottom edge before the light actually comes on, as shown in this video I took.

    OK... that looks faulty. Sorry about that.

    I will send you out another one today.
