Two monitors on one 8800 GTX with Xinerama and kernel 18.104.22.168. If I run driver 195.36.15 and the cuda 3.0 toolkit, there is a CUDA_UNKNOWN_ERROR at cuGLCtxCreate.
Without xinerama, it works. Verified on another computer using 8800 GT.
The beta cuda driver 195.17 with kernel 2.6.32 worked.
I had a similar problem once with two graphics cards, and it turned out to be one card was malfunctioning. But this seems to be another problem.
Does anyone have a working Xinerama cuda 3.0 interop program?
