Is a Desktop Experience on ARM with X11 Possible?

[Mattias Eliasson]

It depends on the platform. On Raspberry Pi x11 doesn't support hardware acceleration. That's an x11 issue not a JFX issue. I'm currently gonna implement a very limited desktop environment for this platform specifically, although it should work on any ARM platform that can run JFX.

To make x11 and OpenGL mix well you need a good backed renderer for x11. If you can't get windows decoration on OpenGL windows that's probably because your platform doesn't use OpenGL for the window manager. That used to be a problem on x86 before they made x11 render everything using OpenGL. But the problem is that ARM usually has EGL which is not yet fully supported by x11. There may be support for some GPU:s but don't count on yours being supported.
