[Graham Inggs (ginggs)]

I think the problem here is that python-pyopencl depends on the virtual package opencl-icd (i.e. it needs an OpenCL ICD), but although AMD graphics drivers do ship an OpenCL ICD, they do not indicate this by providing opencl-icd.

Installing nvidia-opencl-icd-331-updates alongside AMD graphics drivers should cause any problems as multiple OpenCL ICDs from different vendors can be co-installed.

See also LP: #1129409, this was fixed for the Nvidia graphics drivers, but never for the AMD graphics drivers.

That should be:

Installing nvidia-opencl-icd-331-updates alongside AMD graphics drivers should *not* cause any problems as multiple OpenCL ICDs from different vendors can be co-installed.

[Graham Inggs (ginggs)]

See comment 86 of LP: #1129409.
Both fglrx-core and fglrx-updates-core should Provides: opencl-icd as they both ship /etc/OpenCL/vendors/*.icd.
