Reinstall that intel driver you downloaded previously. then use the following command to prevent Ubuntu automatically updating the package sudo apt-mark hold xserver-xorg-video-intel Ubuntu will always try to upgrade that package because there are more recent versions of it. The above command will prevent Ubuntu automatically upgrading it. It will still appear in your package update dialogue that pops up but unchecked. Just don't mark it for upgrade yourself in that and you will be fine. On Thu, May 16, 2013 at 4:28 PM, Juan Pablo Rinaldi
