--- Comment #14 from Erik Kurzinger <ekurzin...@nvidia.com> ---
Bar1 is the portion of video memory that can be accessed by the CPU over PCIe.

And yes, a graphical desktop environment would be expected to utilize GPU
memory bandwidth, but only if you're actually interacting with it. If it's just
sitting idle then it wouldn't be surprising that nvidia-smi reportes 0% mem
utilization.

Could you try running "nvidia-smi dmon" and, moving windows around or
activating some desktop effects? This should cause the mem and SM values to
increase, unless there really is a bug.
