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


sudo vi /etc/X11/xorg.conf.d/20-intel.conf

On newer Ubuntu / Mint / Debian systems the file would go in: /usr/share/X11/xorg.conf.d/20-intel.conf
 

Type "i" and enter the following:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod" "sna"
   Option      "TearFree" "true"
EndSection



Be sure to use this guide with the correct quotes " (if they have a nice curve to them they are wrong and will cause your graphics/Xorg to not work).

You don't even need to restart your whole computer but you could just hit "Control + Alt + Backspace"

If you have an error when restarting you probably have the wrong curved quotes from somewhere else.

The above is happening once again due to wrong quotes coming from some bulletin boards and Wordpress blogs.  Make sure your quotes are straight like this " and not curved.  If they are just delete manually and requote and restart.
