Hi Tina. The problem is that DirectFB can not find the system module. If you want to use the frame buffer, please put "system=fbdev" in your directfbrc (without the quotes). I think there are 2 possibilities that can be wrong. (1) you have not build the fbdev system module. This is called libdirectfb_fbdev.so. Try to find it on your Target File System. (2) you have not put this module in the correct location. On my PC it is in /opt/local/lib/directfb-1.3-0/systems/, but it will be different on your system. You can take a look in your makefile, there should be a definition called MODULEDIR. DirectFB will try to find the system module in MODULEDIR/systems.
