When I start fglrx-amdcccle (Catalyst control center), I get the following message:
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.
What should I do to make it work? Note: I boot Ubuntu with nomodeset.
