hi, all
I am writing a gfxdriver for Fujitsu mb86296 video card under DirectFB. When I run a example df_fire from DirectFB-examples-1.0.0.tar.gz, there is  no output on the computer screen, it is black completely, and the error result looks like this:

I wonder if it is wrong in my code in mb86296_screen.c which I refer to sh7722 gfxdriver, here is the code:

/**********************************************************************************************************************/

static DFBResult
mb86296InitScreen( CoreScreen           *screen,
               CoreGraphicsDevice       *device,
               void                 *driver_data,
               void                 *screen_data,
               DFBScreenDescription *description )
{
          /* Set the screen capabilities. */
     description->caps = DSCCAPS_NONE;

     /* Set the screen name. */
     snprintf( description->name, DFB_SCREEN_DESC_NAME_LENGTH, "MB86296 Screen" );

     return DFB_OK;
}

static DFBResult
mb86296GetScreenSize( CoreScreen *screen,
                  void       *driver_data,
                  void       *screen_data,
                  int        *ret_width,
                  int        *ret_height )
{
     *ret_width  = MB86296_LCD_WIDTH;
     *ret_height = MB86296_LCD_HEIGHT;

     return DFB_OK;
}

ScreenFuncs mb86296ScreenFuncs = {
     InitScreen:    mb86296InitScreen,
     GetScreenSize: mb86296GetScreenSize
};

In driver_init_driver(), I called dfb_screens_register( device, driver_data, &mb86296ScreenFuncs ).

anybody can help me??
