NVRM: loading NVIDIA UNIX x86_64 Kernel Module 352.99 Mon Jul 4 23:52: nvidia: module verification failed: signature and/or required key missing - tainting kernel nvidia: module license ‘NVIDIA’ taints kernel. Output of dmesg after reboot and one invokation of deviceQuery is as follows: The situation was not resolved after reboot :( No change when running deviceQuery with root privileges either.

My question is, how to continue troubleshooting in this circumstance?Ġ1:00.0 VGA compatible controller: NVIDIA Corporation GM200 (rev a1)Ĭrw-rw-rw- 1 root root 195, 0 Jun 30 15:39 /dev/nvidia0Ĭrw-rw-rw- 1 root root 195, 255 Jun 30 15:38 /dev/nvidiactl I would suspect this means the driver was not installed properly after all. The one odd detail that I have found so far is the output of cat /proc/driver/nvidia/gpus/0000:01:00.0/information which contains a lot of question marks. This despite the fact that lspci detects an nvidia gpu and the driver reports itself as being installed.
I have subsequently uninstalled and reinstalled the complete cuda packaged (including all dependencies) using apt-get remove and apt-get autoremove.Īfter reinstallation the output of the deviceQuery example is “cudaGetDeviceCount returned 38 -> no CUDA-capable device is detected”. I’m having an issue with cuda 7.5 on ubuntu 15.10 after I did an apt-get upgrade.
