Need help with Linux runtime

#1

I updated my Ubuntu to latest Mesa drivers Mesa 20.2.6. But still get complains about Vulkan and not starting. Any advice?

Hi, what’s your GPU? Could you send the logs from terminal?

We tested Nvidia only with proprietary drivers, but I’m still investigating this issue, for now could you check the following?

  • Try to run vkcube;
  • Make sure you have mesa-vulkan-drivers and vulkan-utils installed;
  • Try to run engine with VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json bin/Debug/the-machinery or VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/intel_icd.x86_64.json bin/Debug/the-machinery
  • Make sure you have vulkan-validationlayers installed and run The Machinery with --vulkan-validation argument
  • Give us the result of vulkaninfo command

I will check on Monday. Currently on windows machine. And no problems.

Ok, it’s seems to be related to Vulkan support on your machine. Try step 2 and check vkcube again
