Q:

confused about which graphics driver is loaded

Using Ubuntu 12.10, and I have 2 graphics card, Intel and ATI, and I finally get proprietary ATI driver to work -version 13.1-, but when I check lshw and lsmod, I get confused.
Here's the output of lshw -the confusing part is the driver property-:
*-display
                description: VGA compatible controller
                product: Cape Verde [Radeon HD 7700M Series]
                ...
                configuration: driver=fglrx_pci latency=0
                ...

*-display
             description: VGA compatible controller
             product: 3rd Gen Core processor Graphics Controller
             ...
             configuration: driver=i915 latency=0
             ...

and Here's lsmod output:
lsmod | grep radeon > returns nothing after I installed the ATI driver

lsmod | grep fglrx
fglrx                5196783  116

lsmod | grep video
video                  19335  1 i915

I expected the video value to be fglrx_pci or fglrx not i915,
am I missing something here?

A:

lshw shows you the hardware that is installed in your PC. Two times display is ok, when you have two graphiccards.
lsmod shows you the loaded modules. You have two graphiccards, so I think it is no problem that the modules for both are loaded.
Both commands doesen't show you which driver is loaded or used.
EDIT: You can try this: glxinfo | grep render
