** Description changed: [Impact] Users with proprietary Nvidia graphics drivers are unable to co-install CUDA and OpenCL applications. The patches in comment #21 and #22 backport the fix from Utopic and resolve this issue by allowing nvidia-opencl-icd-* (Nvidia's OpenCL ICD) to be co-installed with ocl-icd-libopencl1 (the generic OpenCL ICD loader). - [SRU Verification Test Case] + [SRU Verification Test Case #1] + sudo apt-get remove nvidia-opencl-icd-* nvidia-libopencl1-* ocl-icd-ibopencl1 + + sudo apt-get install nvidia-opencl-icd-331 + + With the 331.38-0ubuntu7 drivers, the Nvidia OpenCL ICD will be + installed without any dependencies. + + With the 331.38-0ubuntu7.1 drivers, ocl-icd-libopencl1 will be installed + as a dependency: + + The following extra packages will be installed: + ocl-icd-libopencl1 + Suggested packages: + opencl-icd + The following NEW packages will be installed: + nvidia-opencl-icd-331 ocl-icd-libopencl1 + + Repeat the above for nvidia-opencl-icd-331-updates. + + [SRU Verification Test Case #2] sudo apt-get install nvidia-opencl-icd-331 OR sudo apt-get install nvidia-opencl-icd-331-updates (does not require an Nvidia graphics card) sudo apt-get install beignet (an alternate OpenCL ICD) With the 331.38-0ubuntu7 drivers, the Nvidia OpenCL ICD will be removed: The following packages will be REMOVED: - nvidia-opencl-icd-331 + nvidia-opencl-icd-331 The following NEW packages will be installed: - beignet + beignet 0 upgraded, 1 newly installed, 1 to remove and 0 not upgraded. With the 331.38-0ubuntu7.1 drivers, beignet and nvidia-opencl-icd-331 (or nvidia-opencl-icd-331-updates) can be co-installed. [Test Case] sudo apt-get install nvidia-331 or sudo apt-get install nvidia-331-updates (does not require an Nvidia graphics card) sudo apt-get install python-pycuda sudo apt-get install python-pyopencl This will result in the error message below. The following packages have unmet dependencies: python-pyopencl : Depends: libopencl-1.1-1 Depends: libopencl-1.2-1 Depends: ocl-icd-libopencl1 but it is not going to be installed E: Unable to correct problems, you have held broken packages. A similar conflict exists between wine and nvidia-cuda-toolkit. sudo apt-get install nvidia-331 or sudo apt-get install nvidia-331-updates (does not require an Nvidia graphics card) sudo apt-get install wine sudo apt-get install nvidia-cuda-toolkit This will result in a warning similar to the one below. The following extra packages will be installed: nvidia-libopencl1-331 nvidia-opencl-dev The following packages will be REMOVED: ocl-icd-libopencl1 ocl-icd-libopencl1:i386 wine wine1.6 wine1.6-amd64 wine1.6-i386:i386 The following NEW packages will be installed: nvidia-cuda-toolkit nvidia-libopencl1-331 nvidia-opencl-dev [Regression Potential] This fix only affects the relationships between packages and should not introduce any new bugs. However, since packages that were previously difficult to install together will now be co-installable, new bugs in those packages may be exposed. [Other Info] It is possible to work around this issue by first installing the CUDA application, then installing ocl-icd-opencl-dev, and finally installing the OpenCL application.
