Trying to use the Radeon 8790M on my Dell Latitude E6540 running Kubuntu 13.04 (Raring). This laptop also has an Intel adapter (for power saving). lspci gives:
$ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Haswell Integrated Graphics Controller (rev 06) 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Mars [Radeon HD 8790M]
Tried using the standard fglrx and fglrx-update and aticonfig results in (in a message box):
aticonfig: No supported adapters detected
Trying AMD's drivers always renders the same result:
Your graphics adaper is not supported by this driver. Installation will not proceed.
There is no 3D acceleration, as evident by running glxgears:
$ glxgears X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 153 (GLX) Minor opcode of failed request: 19 (X_GLXQueryServerString) Serial number of failed request: 12 Current serial number in output stream: 12
This may be an issue of the multi-adapter situation, but I'm not sure how to resolve this.
