trying to get some sample applications to work


I am trying to get some of the samples to work in the cuda toolkit. some/most work how I use them.

However, I am using X11 forwarding, and for example the Mandelbrot sample code throws me an error:

$ /usr/local/cuda-10.2/samples/bin/x86_64/linux/release/Mandelbrot
[CUDA Mandelbrot/Julia Set] - Starting…
GPU Device 0: "Kepler" with compute capability 3.0

Data initialization done.

Texture created.
Creating PBO…
CUDA error at Mandelbrot.cpp:971 code=999(cudaErrorUnknown) "cudaGraphicsGLRegisterBuffer(&cuda_pbo_resource, gl_PBO, cudaGraphicsMapFlagsWriteDiscard)"

I assume that is because I am doing X11 forwarding, "is there a way around it?"
