Hi all current git head I ran into a strange problem.
The main layer is giving a buffer mode of DLBM_BACKSYSTEM but the
drive is set up to give out DLBM_BACKVIDEO
I had to hack around with this.
if((ret = layer->GetConfiguration( layer, &layerConfig))) {
DirectFBError(
"IDirectFBDisplayLayer::GetSurface() failed", ret );
assert(0);
}
if(layerConfig.buffermode == DLBM_BACKSYSTEM ) {
layerConfig.buffermode = DLBM_BACKVIDEO;
layerConfig.flags = DLCONF_BUFFERMODE;
DFBCHECK(layer->SetConfiguration( layer, &layerConfig));
}
printf(" Layer: format=%d width=%d height=%d buffermode=%d
surface_caps=%d\n",layerConfig.pixel
This is with the X11 backend and the main screen layer
dfb->GetDisplayLayer( dfb, DLID_PRIMARY, &layer )
Now what I can't quite figure out is how this layer ended up configed
to BACKSYSTEM ?
Its easy to replicate just try and lock the primary surface layer with
the X11 backend and it fails.
I'm guessing this is a config error but I've not got buffermode set
anywhere I know of.
Maybe thats the problem. But if so shouldn't the X11 driver set it to
DLBM_BACKVIDEO ?
