This question already has an answer here:
The intel graphics installer seems to be compatible with Ubuntu 14.10, and it wont detect elementary OS freya.
What is the best way to install these drivers?
I'm on a mac mini late 2012 with a Intel HD Graphics 4000
EDIT-- I would like ta add this bonus question because I think it can be useful. How can I clean my system from any earlier attempt to install such drivers? How can I safely go back to same drivers used on a fresh install?
