Hi, Sorry for late reply. Could be that we're not restoring the state properly. Not sure though that we guarantee that the framebuffer contents is valid after unbind. Perhaps take a look at what other drivers do. I see the same issue on my PSB systems which run SDVO so it is at least not LVDS related. Unfortunately I wont have time to look at anything gma500 related at the moment. Feel free to dig into this and I'll also put it on my todo-list.
