But way do it need the
/usr/libdirectfb-1.0-0/gfxdrivers/libdirectfb_matrox.so
I have set the --with-gfxdrivers=none in the configuration.
And how do I change the pixelformat the error accoures in the call
dsc.flags = DSDESC_CAPS;
dsc.caps = DSCAPS_PRIMARY | DSCAPS_FLIPPING;
DFBCHECK (dfb->CreateSurface( dfb,&dsc,&primary));
I have changed the flags and the caps but nothing helps and the API
documentation about the flags dont help much.
