Martin, thanks for testing and for the link. >From that link, it sounds like there is a known issue with cudaMemcpy2DToArray. Would you try some of the samples from 1_Utilities, e.g. bandwdithTest, or even deviceQuery and see if you get the same error?
At this stage, please keep nvidia-modprobe installed. While trying to reproduce this issue, I was also unable to run nvprof as a normal user after removing nvidia-modprobe, but I never see 'Error: Internal profiling error 4168:999'. I've reported this as bug LP: #1767777 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767205 Title: nvprof does not complete without sudo To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-cuda-toolkit/+bug/1767205/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
