Hi all, I'm getting the error

init done 
opengl support available 
OpenCV Error: Gpu API call (all CUDA-capable devices are busy or unavailable) in mallocPitch, file /home/andreas/Downloads/OpenCV-2.4.3/modules/core/src/gpumat.cpp, line 1283
/home/andreas/Downloads/OpenCV-2.4.3/modules/core/src/gpumat.cpp:1283: error: (-217) all CUDA-capable devices are busy or unavailable in function mallocPitch

when I'm trying to run the highgui_gpu_gpu example (with all except the gpumat openGlGpuMatWnd window commented out). So it basically looks like:

 if (haveCuda)
   namedWindow(openGlGpuMatWnd, WINDOW_OPENGL | WINDOW_AUTOSIZE);

 Mat img = imread(argv[1]);

 if (haveCuda)

 GpuMat d_img;
 if (haveCuda)

 if (haveCuda)
            Timer t("OpenGL GpuMat   ");
            imshow(openGlGpuMatWnd, d_img);

I'm using CUDA 5.0, the cuda examples as well as the opencv+cuda examples work.

I built OpenCV with following CMake Flags:

Yes, I've already read that post, and any other I found on that topic, without any luck. Maybe it has something to do with Ubuntu running compiz. But that's just a guess.

btw, if I try to run the unmodified highgui_gpu_gpu example, I also get an error:

OpenCV Error: Assertion failed (buffer_ != 0) in Impl, file /home/andreas/Downloads/OpenCV-2.4.2/modules/core/src/opengl_interop.cpp, line 371 /home/andreas/Downloads/OpenCV-2.4.2/modules/core/src/opengl_interop.cpp:371: error: (-215) buffer_ != 0 in function Impl

Maybe it'a a driver problem. Try to install drivers from NVidia site.
