Hi! AFAIK the "no-vt" option should suppress the vt switch... If you are running the application from the framebuffer console that the directfb apps are supposed to appear on this is unlikely to work, since the framebuffer will be controlled by the console, and the console and directfb will interfere with each other in calls to the framebuffer. If you are running the app from a serial console or Telnet/SSH terminal the no-vt option should work for you.
