[14.04 64Bit]-How To Install Proprietary Intel "Sandy Bridge" HD 
Graphics Driver?

Hi,

Today I installed Kubuntu 14.04 64Bit onto my Zotac ZBox thin client 
desktop.
Everything appears to be working ok, but the system is a little slower 
than preferable.

When I go into Settings/System Settings/Driver Manager
there is no listing for the graphics driver?(Intel "Sandy Bridge" HD 
Graphics)

How do I install latest proprietary Intel HD Graphics display driver 
easily & safely?
Thanks in advance!

Jesse
