VK_KHR_xcb_surface extension missing error

[YandongJi]

Hi,

I'm having this error when running python -m mani_skill2.examples.demo_random_action:

[2024-04-20 11:36:31.505] [svulkan2] [error] GLFW error: X11: Vulkan instance missing VK_KHR_xcb_surface extension

I updated Vulkan SDK, Vulkan Driver, the extension exists as "VK_KHR_xcb_surface : extension revision 6" as well as

"Surface types: count = 2 VK_KHR_xcb_surface VK_KHR_xlib_surface" on RTX 4090 GPU, I tried installing "sudo apt-get install libxcb1-dev libx11-xcb-dev".

I exported these path in bashrc:

export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json #:/usr/share/vulkan/icd.d/intel_icd.x86_64.json:/usr/share/vulkan/icd.d/lvp_icd.x86_64.json
export VK_LAYER_PATH=/usr/share/vulkan/explicit_layer.d/:/usr/share/vulkan/icd.d/
export VK_INSTANCE_EXTENSIONS=VK_KHR_surface:VK_KHR_xcb_surface

But this error still exists. Looking for kind help now.....

Actually using docker it can display the visualization now, but still want to solve this bug

Are you saying it works in Docker but not outside of Docker? Or you are using some other visualization method? Also I think the variable VK_INSTANCE_EXTENSIONS should not be set. You can follow the following steps to debug:

1. Try to get the program vkcube to work (you can probably find more resources on how to debug vkcube). If vkcube won't run on screen, I cannot really give any useful advice.
2. Test maniskill again, if it still does not work, paste the result of nvidia-smi and vulkaninfo here

Hi @YandongJi do you still have this issue?

[YandongJi]

yes, thanks for checking, it still only works in docker, I can look into this a week later

Closing the issue now as it has become stale.
