Eu tento instalar o Cuda 8.0 na minha instalação do Ubuntu 16.04. Minha placa gráfica é uma GTX 760. O driver da Nvidia que estou usando é a versão 375.82 (Open Source). Eu também tentei 384.69, mas isso faz com que minha tela pisque e eu não era capaz de resolver isso, portanto, fique com 375. Drivers proprietários não são oferecidos por Drivers Adicionais.
Agora, meu problema é que, ao compilar as amostras de Cuda, recebo este erro:
/usr/bin/ld: cannot find -lnvcuvid
collect2: error: ld returned 1 exit status
Makefile:381: recipe for target 'cudaDecodeGL' failed
make[1]: *** [cudaDecodeGL] Error 1
make[1]: Leaving directory '/home/till/cuda_samples/NVIDIA_CUDA-8.0_Samples/3_Imaging/cudaDecodeGL'
Makefile:52: recipe for target '3_Imaging/cudaDecodeGL/Makefile.ph_build' failed
make: *** [3_Imaging/cudaDecodeGL/Makefile.ph_build] Error 2
Parece que há uma incompatibilidade entre a versão real do driver usada e a esperada por Cuda. O arquivo libnvcuvid.so é encontrado apenas em nvidia-384 -folders:
/usr/lib32/nvidia-384/libnvcuvid.so
/usr/lib/nvidia-384/libnvcuvid.so

nvidia-smi retorna:
Failed to initialize NVML: Driver/library version mismatch
Como mencionei, não posso usar o driver 384 devido ao problema de tremulação. É possível fazer trabalho de cuda com o driver 375?
