    Get APU + discrete GPU work together on Ubuntu

    isaid

      Hi

      I am trying to install Catalyst 11.10 on Ubuntu 11.10.  When I run a simple OpenCL code

      only the onchip GPU is detected.

      Is there a way to make fglrx detect the second GPU as well?

      thx

          run export COMPUTE=:0

              I already tried that one ... I even exported DISPLAY=:0

              The problem is that even fglrxinfo returns only the integrated GPU ... it does not detect 

              the dgpu (a Cayman) alhough I run aticonfig --inititial --adapter=all

                      As you can see, only the Firepro is detected

                          sorry that wasn't the right output (the first one is about Mesa)

                          her it is :

                              that is strange. try run clinfo from SDK and output attach as code.

                                  I did reinstall the driver 11.10 . Now only the APU is seen as an opencl device, the discrete GPU is not detected:

                                  here is the new fglrxinfo output:

                                                      after that you can duplicate that Device section so it maybe work with both GPUs.
