I have a problem with A10-7850K + R9 290X setup I am using. I have set it up so one display is connected to A10-7850K and one display is connected to R9 290X. Installed 14.3 drives and setup xorg with 2 adapters.
OpenCL seems to work just fine. But Ubuntu is able to use only 1 display for desktop and second display stays black (it is possible to move the mouse pointer there).
I am able to fix the issue by enabling xinerama, but that seems to break composite and I get empty desktop after I login to Ubuntu. The other option is putting both displays to A10 or 290X but then OpenCL does not work.
Do you have any idea about how can I get it working without breaking OpenCL?
