Just got my MSI GX70 with Richland A10-5750M APU and Neptune HD 8970M. Immediately installed Ubuntu 64 and the beta fglrx-drivers. I installed the 13.8 beta, because not 13.6 but 13.4 was promoted as stable and i understood there would be problems using too old drivers.
When doing "aticonfig --lsa", I only got HD8650G listed. My conclusion: the HD 8970M is not supported yet under Catalyst 13.8 beta drivers. Am i correct? If yes, when can I expect to get support? And if no, what should I do to get it working?
