I have manually tried to install AMD Radeon HD 7470M proprietary drivers from AMD official site. But after installing when I tried to launch Catalyst Control Center, a message is shown like this:
There was a problem initializing Catalyst Control Center Linux edition.
It could be caused by the following:
No AMD graphics driver is installed, or the AMD driver is not functioning properly. Please install the AMD driver appropriate for you AMD hardware, or configure using aticonfig.
I am using Ubuntu 64-bit 12.04LTS.
