After spending a lot of time trying to get CUDA Toolkit working, I came up with a very weird situation were the Samples (in special the SobelFilter) is working. But a simple code that I run in Nsight does not appear to work.
I got a Lenovo Ideapad U410 with a Gefore 610M (Optimus Technology). That’s why I’ve installed the Bumblebee project (that it’s working fine).
I run the example like this:
optirun -b none ./SobelFilter
And it works just fine. But when I run my code (tested in other GPU) the image does not appear. It only shows a white image with a lot of black dots.
Another weird thing is that
optirun -b none nvidia-settings
does not appear to work.
Hope you can help me, I’m trying to finish a course of GPU and I need my computer to program.
