Description

Prerequisite: In MESOS-5257 "By default, with no '--nvidia_gpu_devices' flag or `gpus` resources flag, the new auto-discovery will simply enumerate all of the GPUs on the system" and in MESOS-5630 "removes this flag(--enable-nvidia-gpu-support) and enables this support for all builds on Linux."

So, I '../configure' without any flag, and start agent without '--resources' or '--nvidia_gpu_devices' , but can not discovery GPU resources, and I also start agent with '--resources' and '--nvidia_gpu_devices' , it also does not work.

I'm sure the NVIDIA GPUs on my machines are OK, because with '--enable-nvidia-gpu-support' when './configure' and with '--resources', '--nvidia_gpu_devices' when starting agents it works well.
