Well, FBIO_GET_TIMING seems to be not supported in your kernel. In DirectFB, initially, the screen size was fixed, later it was queried using FBIOGET_VSCREENINFO, and currently it is queried with the FBIO_GET_TIMING which is failing below.
I'm not sure if this will lead to further issues, but I noticed that 1 failure case is not handled properly, so you might want to try the following patch: diff --git a/src/core/layer_context.c b/src/core/layer_context.c index d0a71b4..f0360ee 100644 --- a/src/core/layer_context.c +++ b/src/core/layer_context.c @@ -1491,6 +1491,7 @@ build_updated_config( CoreLayer *layer, /* Update source and destination rectangle. */ if (update->flags & (DLCONF_WIDTH | DLCONF_HEIGHT)) { int width, height; + DFBResult ret; flags |= CLRCF_SOURCE | CLRCF_DEST; @@ -1501,10 +1502,11 @@ build_updated_config( CoreLayer *layer, switch (context->screen.mode) { case CLLM_CENTER: - dfb_screen_get_layer_dimension( layer->screen, layer, &width, &height ); - - ret_config->dest.x = (width - ret_config->width) / 2; - ret_config->dest.y = (height - ret_config->height) / 2; + ret = dfb_screen_get_layer_dimension( layer->screen, layer, &width, &height ); + if( ret == DFB_OK ) { + ret_config->dest.x = (width - ret_config->width) / 2; + ret_config->dest.y = (height - ret_config->height) / 2; + } /* fall through */ case CLLM_POSITION: Otherwise, you should either revert the fix done on davinci_screen.c http://git.directfb.org/?p=core/DirectFB.git;a=commitdiff;h=d261c76eb8c8a53bc8e2132f6b8905b58a01340d or update/patch your kernel.. There are some DaVinci kernel patches floating around..
