G2H2 modules, with Qt 5.3.2, use Qt’s EGLFS platform, which takes advantage of the GPU and hardware acceleration. Qt manages the the frame buffer. We are not running a display server, X11 or Wayland.

G2C1 modules, which have no GPU, with Qt 4.8, use QWS to manage the frame buffer. Again, there is no display server such as X11 or Wayland.
