    I downloaded qt4-embedded on my Beaglebone black to run a qt gui on my BBB and display it on a touchscreen but I'm having calibration issues such as:

    root@beaglebone:~# ts_calibrate
    xres = 1024, yres = 768
    tslib: Selected device is not a touchscreen (must support ABS and KEY event types)
    

    some other references:

    root@beaglebone:~# opkg install tslib-calibrate
    Package tslib-calibrate (1.0+gitrAUTOINC+e17263ef401ee885a27d649b90b577cfb44500e0-r9.2) installed in root is up to date.
    root@beaglebone:~# uname -a
    Linux beaglebone 3.8.13 #1 SMP Wed Sep 4 09:09:32 CEST 2013 armv7l GNU/Linux
    

    I have an angstrom OS installed on my BBB.

    Do not wait to innovate.

      Hi,

      Did you verify that your touch screen is indeed supported by tslib ?

      You should also check that with the BBB folks as it's currently a problem not related to Qt.

        @SGaist Thanks, I found the solution by myself.
