in your scenario, nitpicker is the only component that accesses the
physical framebuffer (provided by the VESA driver). L4Android merely
accesses a virtual framebuffer. The framebuffer and input sessions of
L4Android are routed to a nit_fb instance called "android_fb". This
nit_fb component, in turn, tries to open a nitpicker session to display
the virtual tramebuffer on screen. Since you left nitpicker
unconfigured, it won't display anything from "android_fb" on screen.
