    Hello guys, currently working on project for Linux platforms. Just transferred project to 5.6.2.
    Ubuntu 17.04 Dell All-In-One. Build on windows for Linux x86_64. Build is running, but touchscreen can't figure out that clicking at monitor, but it recognizing my touch anyway... so if I hold my finger on any button and perform click by mouse it does click the button, but not by touching display.
    Problem came only with 5.6.2, build from 5.3.5 working good. Hopefully developers from Unity can see this thread, because don't know where to post bug reports.

    Update: No Button, no Event Trigger components reacts on touch (OnClick() function).

    In event trigger component (PointerEnter works, PointerDown works, PointerClick doesn't)

    Same problem here. Oddly, a resistive touch screen still works fine but a optical one doesn't. I'll dig up model numbers and OS rev and report back, but at least adding this bit of info for what it's worth.

    On Fedora 25 with Unity 5.6.2f1 and 2017.1.0f3:
    • (Resistive touch) Planar PT1745R-BK = WORKS
    • (Optical touch) ViewSonic TD2220 VS14833 = DOES NOT WORK
    With Unity 5.5.2f1 and all else the same, both devices work.

    This issue is still present in 2018. Touch input on Linux is unusable.

    This is pretty unfortunate since we make interactive displays for a kids' museum and linux really does make the most sense for a kiosk like that.
