At the moment LibGGI doesn't "auto detect" framebuffer devices.  There
are two ways to force it:

    1) export FRAMEBUFFER=/dev/fb0

       The FRAMEBUFFER env. var is (AFAIK) a standard used by the
       linux-m68k folks.  LibGGI will detect this env. var and then use
       the fbdev target (just like it detects the DISPLAY env. var and
       uses the X target).

    2) export LIBGGI_DISPLAY=fbdev

Note that vgafb.c is text-only, so not much will work on it.  Try using:

    export LIBGGI_DEFMODE=80x25T

and demos/demo and demos/stars and demos/dots should work.

Hope that helps.

Cheers,
