I'm wondering if following is possible : I have two graphics cards - ATI and Intel, and installed fglrx driver. In amdcccle I have enabled Intel card. I'm developing OpenCV application where I have many computations so I decided to use OpenCL ( OpenCV has ability to use OpenCL ). But is it possible to use ATI card with OpenCL while Intel is enabled in amdcccle? I have tried to use ATI when Intel is enabled but OpenCL ATI GPU adapter isn't detected. But lspci still shows ATI card so maybe it is possible.
