Calibration issues with a touchscreen

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.

Thanks but I found it by myself…!
