  <p>I got mesa 10,but OpenGL is still 3.0.I found some people say <a href="https://askubuntu.com/a/256798/104412">Intel Graphics doesn't support OpenGL 3.3 yet.</a> but some say  <a href="https://stackoverflow.com/a/21567167/1278112">in the last official release of Mesa (10.0), GL 3.3 only works on Intel hardware.</a>
  but some people <a href="https://stackoverflow.com/a/20589728/1278112">work out.</a> </p>
  
  <p>Does Ubuntu 12.04 support OpenGL 3.3?</p>
  
  <p>Does Intel Graphic support it?</p>
  
  <p>What should I do to enable GL3.3</p>
