    Hi,

    I'm trying to setup a preassembled PiScreen on a fresh, latest Wheezy image. I've managed to get the console and XWindow to display on the screen, and it displays the test image, command prompt and GUI just fine.

    However, no touch events seem to be generated, ever. I've tried with evtest and ts_calibrate. The touch screen shows up as event1 (a keyboard is event0), and shows the name when I run:

    cat /proc/bus/input/devices.

    Any idea what could be causing this? I've updated the pi image, as well as tried rebooting and reinstalling drivers.

    I am sorry you are having issues.
    Can you please test with this image;

    Hi Mark,

    Thank you for the prompt response!

    Unfortunately, I've already tried with the prebuilt image. It gives me the same issue.

    can you show me the output of these three commands;

    sudo vcdbg log msg
cat /boot/config.txt
cat /etc/modules

    Also, can you please run 'evtest' and select the event next to ADS7846.

    when it is running tap the touchscreen... you should see some data printed to the screen.
    can you please show me this data.

    Running evtest starts the program, but tapping on the screen generates no data.

    You missed 'sudo' in front of 'vcdbg log msg'
    The command should be 'sudo vcdbg log msg'

    Can you add 'xohms=1' to the config line in /etc/config.txt so i appears line the line below;
    dtoverlay=piscreen,speed=16000000,rotate=90,xohms=1
    and then rerun 'sudo vcdbg log msg'.. and also test if you see any events with evtest

    I didn't miss the sudo. I'm logged in as the root user.

    I'm assuming you meant to edit /boot/config.txt. Doing so results in no change for the vcdbg command, and still no data while running evtest.

    I need to see the logs from 'sudo vcdbg log msg'

    Can you please run
    sudo apt-get update && sudo apt-get upgrade

    Then rerun
    sudo vcdbg log msg

    When you tested with PiScreenImage-SDCard-1.8.zip, did you make any other changes?

    Hi,
    I've just received my PiScreen today. After setup and I cannot get touch events 🙁

    I've tried to setup a preassembled PiScreen on a fresh, PiScreenImage-SDCard-1.8.zip. I've managed to get the console and XWindow to display on the screen, and it displays the test image, command prompt and GUI just fine.
    But touch still doesn't working. I get no output when I run:

    sudo TSLIB_FBDEVICE=/dev/fb1 TSLIB_TSDEVICE=/dev/input/event0 ts_print
