Create um new directory

sudo mkdir /etc/X11/xorg.conf.d/


The information below are within a conf file. within the new directory

echo -e 'Section "Device"\n Identifier "Intel Graphics"\n Driver
"Intel"\n Option "AccelMethod" "sna"\n Option "TearFree"
"true"\nEndSection' | sudo tee /etc/X11/xorg.conf.d/20-intel.conf


Then restart your computer.

Title:
  screen tearing during video in unity 2d (but not ubuntu classic)

Status in unity-2d:
  Confirmed
Status in unity-2d package in Ubuntu:
  Confirmed

Bug description:
  During video playback (any player) horizontal lines form briefly
  during high-action scenes, making it annoying to watch except in low
  resolution.  This is not the case in ubuntu classic.  My video card
  is:

  00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) (prog-if 00 [VGA controller])
  	Subsystem: Sony Corporation Device 9025
  	Flags: bus master, fast devsel, latency 0, IRQ 47
  	Memory at e8400000 (64-bit, non-prefetchable) [size=4M]
  	Memory at d0000000 (64-bit, prefetchable) [size=256M]
  	I/O ports at 8130 [size=8]
  	Expansion ROM at <unassigned> [disabled]
  	Capabilities: <access denied>
  	Kernel driver in use: i915
  	Kernel modules: i915

  so the usual nvidia fixes on the web don't apply.  I've tried
  disabling compositing and transparency effects (as I started noticing
  them at around the same time) but to no avail.
