I installed AMD Catalyst drivers from Additional drivers, after download and installed it, computer asked to restart, but I didn't see that drivers installed while I'm booting. I need to run the OS in nomodeset.
When I open the catalyst in the applications it shows the following error:
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 have this Graphics Card: AMD RadeonHD 7470M 1GB.
