    Ubuntu 14.04 Release: OpenCL cannot see cards

    troymcclure

      Hi,

       

      I have installed today the official Ubuntu Trusty 14.04 release. I downloaded and installed latest beta AMD driver and AMD APP SDK.

      Here is aticonfig --lsa:

      ~$ sudo aticonfig --lsa* 0. 01:00.0 AMD Radeon R9 200 Series                           

        1. 02:00.0 AMD Radeon HD 7900 Series

        2. 03:00.0 AMD Radeon HD 7900 Series 

        3. 05:00.0 AMD Radeon HD 7900 Series

       

       

      * - Default adapter

       

      Unfortunately, clinfo sees only 1 GPU:

      ~$ clinfo | grep GPU

        Device Type: CL_DEVICE_TYPE_GPU

      ~$

       

      fglrxinfo also sees only one. As for lspci:

       

        Device Type: CL_DEVICE_TYPE_GPU

      ~$ lspci | grep ATI

      All worked fine before I upgraded from 13.10.

      Please help I really need this to work.

       

      Thanks a lot in advance.
