Vulkan breakage

[Celejar <celejar@gmail.com>]

Hi,

On my system - an HP Zbook Fury G8 with Intel UHD iGPU + Nvidia Quadro
T1200, running Sid - I think I have all the necessary GPU driver,
tools, and Vulkan pieces installed (all from the official Sid repos),
but Vulkan isn't working properly.

Vulkaninfo doesn't work when run as an ordinary user:

~$ vulkaninfo --summary
ERROR at ./vulkaninfo/./vulkaninfo.h:1413:vkGetPhysicalDeviceSurfaceSupportKHR failed with ERROR_INITIALIZATION_FAILED

Debug messages don't seem to show the problem, just that the failure
occurs when trying the first GPU in its list, the Intel iGPU:

~$ VK_LOADER_DEBUG=all vulkaninfo --summary

...

[Vulkan Loader] DRIVER:         vkCreateDevice layer callstack setup to:

ERROR at ./vulkaninfo/./vulkaninfo.h:1413:vkGetPhysicalDeviceSurfaceSupportKHR failed with ERROR_INITIALIZATION_FAILED

Vulkaninfo works fine when run as root:

~# vulkaninfo --summary
'DISPLAY' environment variable not set... skipping surface info

I don't know if the difference between running as user or as root is based on the difference in
permissions or the difference in environment.

Vkcube runs fine (when run as an ordinary user):

~$ vkcube
Selected WSI platform: xcb
Selected GPU 1: NVIDIA T1200 Laptop GPU, type: DiscreteGpu

[spinning cube displays]

Vkmark works with the Intel iGPU but not with the Nvidia GPU:

Any ideas?
