Hi, Could you try the latest xserver-xorg-video-intel (2:2.0.0-5 currently in experimental) and report back whether it works better? Your DRI problems apparently got solved by removing the VideoRAM line. The blue XV problem should be fixed by now. So what remains is the freeze when a game changes the resolution, and the drmWaitVBlank warning. The latest package has a good chance of fixing these too. Thanks, Brice
