I have an older Trinity laptop with an A10-4600M and I just bought a Richland A10-6800K for a new desktop.

I tried many distros, but the results are the same so I am limiting the discution to Linux Mint 15 x64.

If I use the iGPU in the APU with any fglrx version I get horrible corruptions in most games in my Steam library. However, if I enable and use the dedicated 7670M on the notebook, or a dedicated 7750 on the desktop ( after re-installing fglrx, of course ) most games work OK-ish ( for an ATI/AMD blob it is more than OK )

Many games, like 'The Cave', which isn't very demanding ( like most linux ports on Steam ) have horrible artifacts that look like bad shaders.
Even Valve's own TF2, for example, although renders correctly, feels very 'choppy' although the internal FPS counter ( activated from dev console ) never drops below 40.

Most of these problems dissapare when I switch to the dedicated card.

Clearly, since with the same driver works with the discrete card but not with the iGPU, there is a problem with the drivers for the APU ? Anyone else there with a Richland A10 ?

Thank you.
