You need to calibrate your device.

Do you have xinput_calibrator_once on your rootfs?

[vishvapathi]

No.. There is no xinput_calibrator_once in my rootfs and there is no pointercal in my /etc....

[daiane_angolini]

Yes, and if you´re using TSLIB calibrator, you may not want xinput_calibrator... Sorry for my confusion.

for tslib I think it´s /ts_calibrate

pointercal is a file that will be created by the calibrator binary. So, if you don´t have it, your system is not calibrated.

You may try to use an example one from some other source, but the recommended is use the calibrator app and create your own pointercal
