I'm wondering if this is anyhow related to the driver that I wrote. > I did the modification as Richard said and what happens is that > DLBM_BACKVIDEO returns "out of video memory" (I´m having lot of trouble > about this "out of video memory" in general. Maybe there is some DirectFB > configuration where I can make some changes on it. Specially about > CreateSurfaces) I don't know about the layer implementations in your driver and how much video memory is available. But if you're having problems with out of video memory messages when using the primary layer, it might be a limitation or bug in the frame buffer driver. > Using DLBM_BACKSYSTEM it seems to be working fine.
