Cuda 10 and optix Linux doubts and questions

Impossible to install cuda 10 from 0 and optix in linux, it may be a problem of compatibility between cards ?.

I also have the problem compiling everything cuda toolkit with “runfile (local)”. This installs the driver 418.xx but I no longer recognize the rtx if the gtx.
I get it every time I want to install cuda 10.

dpkg: error processing archive /var/cache/apt/archives/libcublas-dev_10.1.0.105-1_amd64.deb (–unpack):
trying to overwrite ‘/usr/include/cublas_v2.h’, which is also in package nvidia-cuda-dev 9.1.85-3ubuntu1

dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)

The problem is that there is a display driver contained inside the CUDA Toolkit at all. It doesn’t know of any products released since the CUDA toolkit shipped and is outdated the moment an official driver release with support for that CUDA version becomes available.

That’s one of the most often asked questions in the “CUDA Setup and Installation” sub-forum.
