  1. I suggest upgrading your graphical stack.

    Run in terminal

    sudo apt-get update
sudo apt-get upgrade
sudo apt-get install xserver-xorg-lts-trusty libgl1-mesa-glx-lts-trusty libgl1-mesa-glx-lts-trusty:i386
sudo apt-get install xserver-xorg-input-all-lts-trusty

    This will upgrade Intel driver too and your system should be 12.04.5.

  2. You should use following drivers Intel Graphics for Linux. Here is GUI Friendly installer: Intel Graphics Installer for Linux. I see that you use version 12.04, seems it's not supperted already.

    I know, that proposition upgrade your current installation to new version is not solution, but I will suggest you.
