Re: JavaFX8: Multittouch support under Linux
Thanks, I’ve applied the patch from the bug tracker, and could compile now. I will get back to you when I have had a chance to run a multitouch application with that build.

The touch support on the Raspberry Pi and similar devices gets events from the Linux device drivers, not from X11 or GTK. We don’t provide a binary of this configuration for x86, but if you are able to build OpenJFX then you could easily create a binary yourself (“gradle -PCOMPILE_TARGETS=x86egl sdk”). This is a hybrid binary that uses EGL/X11 for full-screen output but gets input directly from device nodes in /dev/input.
