USB graphics devices from displaylink does not have 3D hardware. To get 3D effects (compiz, GNOME 3, KWin, OpenGL apps etc) with these device in Linux the native (primary) GPU can be used to provide hardware acceleration. All the graphics operation is done using the native (primary) GPU and the end result is taken and send to the displaylink device. Can this be achieved? If so is it possible to implement a generic framework so that any device (USB, thunderbolt or any new technology) can use this just by implementing device specific (compression and) data transport? I am not sure this is the correct mailing list.
Thanks,
