Depending on the "desktop-buffer-mode" option:
Desktop buffer mode:
desktop-buffer-mode=(auto|triple|backvideo|backsystem|frontonly|windows)
auto: DirectFB decides depending on hardware.
triple: Triple buffering (video only).
backvideo: Front and back buffer are video only.
backsystem: Back buffer is system only.
frontonly: There is no back buffer.
windows: Special mode with window buffers directly displayed.
