    SDK v2.5 fails to find HD6990s?

    rollyng
      Driver 11.7 with SDK 2.5, 4X HD6990 (8 GPUs) on Ubuntu 10.10 x64

      Hi, I have just downloaded and installed 11.7 on Ubuntu 10.10 x64, but found that SDK v2.5 (nou's packages) does not support multiGPUs despite that fglrxifo shows all the 8 devices? It was fine with 11.5+v2.4 ...

      Here is my fglrxinfo output, can anyone help to solve the problem? 

      Thanks!

              Here is the strange output of clinfo which shows only 2 devices but should be 9...

                  I'm having the same issue with 2x HD6970. The clinfo utility shows only one CPU and one GPU device.  This is on a headless RHEL 6.1 server.

                  Maybe the "now supports headless" feature only applies to Windows? :(

                      Thank you jholewinski, my only solution is falling back to 11.5 with SDK 2.4 which works fine except segment fault if triggering debug (GDB).
