[Mesa-users] Is xvfb (with Mesa 19.2) compatible with Vulkan?

[Vijay Pradeep]

Hi Mesa team,

I'm trying to run a Vulkan-based graphical application on a headless Ubuntu
19.10 virtual machine, via XVFB (with Mesa 19.2.1), and unfortunately I'm
getting a VK_ERROR_INITIALIZATION_FAILED error from the Vulkan API.

*Question:* Is it reasonable to expect that vulkan apps would work with
xvfb on Ubuntu 19.10?  Note that Ubuntu 19.10 ships with Mesa 19.2.1, which
claims to support the Vulkan 1.1 API.

FYI: I've cross-posted a more detailed error report on stackoverflow:

Thanks in advance for your help,
Vijay
