ESXi VGPU utilization reflects "0"
Starting with vSphere 7.0 Update 1, Xorg is no longer needed for graphics devices operating in vGPU mode. Consequently, Xorg might not automatically start when using vGPUs. This change won't affect the process of assigning vGPU profiles to virtual machines.
If you're using an NVIDIA GPU with MIG (Multi-Instance GPU) enabled, skip to step 3.
