I want to see the GPU usage of my graphic card. I use on Kubuntu 14.04 LTS x64, with two Nvidia GTX 690 cards. When I run nvidia-smi -q I get:
francky@francky-Aurora-R4:~$ nvidia-smi -q

Why is the GPU utilization N/A, and how to fix or circumvent the issue? I just want the GPU utilization and and I am fine using another tool for that.
Normally, the GPU utilization would be displayed as follows:
nvidia-smi -q
