I installed “deb (local)” cuda-repo-ubuntu1404-7-5-local_7.5-18_amd64.deb package on Kubuntu 14.04. The CUDA toolkit related packages allows as a dependency only nvidia-352 driver package.
So users who install CUDA from nvidia download site are stuck to nvidia-352 driver version and they can not upgrade the driver from repositories or PPA’s while maintaining CUDA installed. For example from here:
If you try to install any driver from that PPA, then CUDA related packages will be uninstalled.
Please rebuild CUDA packages you offer to download, allowing higher driver versions than nvidia-352 (or higher versions than the driver version that you choose include when creating packages).
