Radeon 8750M not recognised on Kubuntu 13.10

[Peter Lopen]

Radeon HD 8750M is not recognized using Fglrx-installer 13.101. It needs proprietary drivers at least Catalyst 13.11 beta 6. Then X org recognizes it, but there is an error during initialization, possibly because of version incompatibilities as Catalyst supports only Ubuntu 13.04.

Error during X startup:
