How do I find out which driver a piece of hardware is using?

I recently installed Ubuntu 12.04 as a fresh install. I followed the Unofficial Wiki to install the AMD catalyst driver version 12.4 from source.

In Gnome3 under 'All Settings' 'Details' 'Graphics' is shows Driver as VESA: BROADWAY. Is this correct?

fglrxinfo shows:

display: :0  screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: ATI Mobility Radeon HD 5800 Series
OpenGL version string: 4.2.11631 Compatibility Profile Context

Xorg.conf show the fglrx Driver being used:

Running gfl_glxgears shows a 3D rotating cube. How can I confirm Gnome is using the correct driver? Any assistance appreciated.

im pretty sure that your installation worked correctly. I have the HD4850 one and after installing the closed source drivers got the same information.
