While I was trying to connect the device to an external display, the internal display touchscreen is been recognized as non-touchscreen and the external display is been recognized as a touchscreen. Is there a way to fix this by changing the kernel argument or some patchs? Let me know what log do you need.

The device I am using is HP Engage One I/O Base Model: TPC-I026-D.

I tried to enable the Touchscreen Calibrating in chrome://flags, turns out the system recognize the touchscreen is located at the external display.

The touchscreen allocate correctly without external display attatched, but as it is connected, the touchs goes to the external display.
