The issue is summarized in the subject of this post, when on my laptop I click System > Preferences ATI Catalyst Control Center I get this message:
Initialization error: There was a problem initializing Catalyst Control Center Linux edition. It could be caused by the following. No ATI graphics driver is installed, or the ATI driver is not functioning properly. Please install the ATI driver appropriate for you ATI hardware, or configure using aticonfig.
Some detail about environment:

I have installed ATI proprietary driver using "Additional Drivers" and Jockey says that the driver is activated and currently in use. After driver installation I'm able to use a resolution of 1366x768. I'm using classic interface (no Unity).
