    What difference between "VGA compatible controller" and "Display controller"?

    natasha

      In my Lenovo IdeaPad G500A (59-381065) (openSUSE 13.1) I have the following graphics system:

      Intel HD Graphics 4000 and AMD Radeon HD 8750M;

      #  lspci | grep 'VGA\|ATI'

      00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

      01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Mars [Radeon HD 8670A/8670M/8750M]

       

      In forums.amd.com/Support of HD 8750M and linux drivers 14.501.1003 or beta the user with the same AMD GPU has

      lspci | grep VGA

      00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

      01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mars [Radeon HD 8670A/8670M/8750M] (rev ff)

       

      What difference between these two AMD cards, or, more generally, what difference between VGA compatible controller [0300] and Display controller [0380] PCI classes?
