Allow list for Smart Virtual Background for Linux and Windows

All of Zoom's Linux VDI plugins support the Smart Virtual Background (Virtual background without a green screen) feature. If your device meets the hardware and software requirements below, the Smart VB feature will be enabled automatically. There are additional libraries for the Linux operating system that are required to support the new functionality.

This article covers:

Prerequisites for the Smart VB feature allow list

Additional library requirements

If you are using a software package from a vendor such as iGel, Dell, and HP, please check with the vendor to determine if there is an update available that contains these libraries. Zoom works closely with our partners, and new releases of both the operating system and Zoom VDI Plugin may be available.

The following libraries must be added to any Linux operating system for the new functionality to work.


OpenCL requirements

Some Thin Client models can leverage the GPU to optimize performance and reduce load on the CPU. For models where the GPU can be used, there is a requirement for Intel-OpenCL runtime to be OpenCL 2.1 or higher.

If an older version of OpenCL is installed or the thin client model does not support using the GPU, the Smart VB feature will use the CPU to support the functionality required.

VDI hardware requirements

The following platforms have been tested for Smart VB functionality.

In addition to the CPUs that meet the specified system requirements, Zoom VDI Client also supports the virtual background for the following CPUs with 360p x 15FPS video for both Windows and Linux.

How to enable Smart Virtual Backgrounds for Linux

Zoom automatically enables Smart VB for the models indicated in the above table and for any client with matching capabilities. For models that do not satisfy hardware requirements, the lack of the SmartVB feature will only allow selecting a virtual background if a green screen is selected.

While Zoom has worked carefully to verify that the hardware requirements will ensure the Smart VB works as expected, it is possible to manually override the limitations imposed by the allow list to test devices that are not automatically enabled for Smart VB. Zoom does not recommend using this option to override the allow list except for testing. After testing, if your results suggest the allow list could include a model not currently supported, please contact Zoom to share your test findings.
