I'm trying to calibrate my iiyama touch screen on my new raspberry pi 3.

I installed LIBTS for this :

sudo su
aptitude install libts-bin

Then I have to export two variables LIBTS_FBDEVICEand LIBTS_TSDEVICE.

I tried this :

export TSLIB_TSDEVICE=/dev/input/event1
export TSLIB_FBDEVICE=/dev/fb0

I found those values in the /dev and /dev/input directory, I checked multiple times to make sure they are the correct ones.

When I run ts_calibrate or ts_test , I keep receiving this error :

selected device is not a touchscreen I understand

Do you have any idea why ? Thanks

I ended up using another tool :

xinput_calibrator
