Does Unity support multiple touch screen on Linux?

Hello there,

We are running into some issue with multple touch screen on Linux(Fedora 28). The application is developed with Unity3D 2019. Our program has three video display, two of them are LCD with touch screen. One touch screen 1920* 1080 and the other touch screen 1280*800. The programs set three Camera.

Here are two issues we found
1) One of touch screen cannot detect the correct touch position, the position shift quite a bit.
2) If I touch one of screen, all three screen will respond to the touch event.


It seems Unity cannot detect and distinguish two touch screen. I am not issue it the latest U3D support multiple touch screen (or multiple mice) on Linux (Fedora 28) or not.

We veryfied QT application can detect touch event and response properly. Also If we start multple shell window. The command window can detect which screen get touched. So there is no problem with device driver.

I am wondering if U3D support multiple touch device (mice) on Linux (Fedora 28) or not. If yes, anything we are missing?

Thanks
