    HD7850 not detected under Linux

      Hi,

       

      I have a HD7850 on a 64bit OpenSuse 11.4. I have the newest Catalyst driver and APP SDK installed. When I use clinfo it only lists the processor.

       

      There is an X server running but the display is connected to the integrated graphics of the Intel processor and not the HD7850. I already found [1] and now have only

      Section "Device"

              Identifier  "aticonfig-Device[0]-0"

              Driver      "fglrx"

              BusID       "PCI:1:0:0"

      EndSection

      in my xorg.conf. The PCI id is correct (confirmed with lspci) and fglrx is also loaded. According to the xorg.log it does not seem to get initialized.

       

      The card still does not show up.

       

      Connecting the monitor to the HD7850 and using the default settings from aticonfig --install ends up working. That's not what I want in the end though. As I said I would like use the HD7850 as a plain compute device and the integrated graphics for output to the monitor.

       

      How can I accomplish this?

       

      Thanks
