Steps to reproduce: Just execute

Minimal reproduction project: N/A

Can you run any Vulkan application?

[Calinou]

This is completely unrelated to the issue itself, but TIL GitHub lets you write bold in code blocks if you use a <b> tag within a <pre> tag (don't use triple backticks for the code block):

I learn something new every day. :no_mouth:

[Juankz]

I've seen this error, you need to install vulkan-validation-layers. And reboot

[nonunknown]

@Juankz vulkan-validation-layers this package doesnt exist. Also I tried LunarXchange sdk and when I run vkvia I get: VIA_ERROR: Vulkan failed to find a compatible driver. maybe my potato laptop doesnt support vulkan.

unrelated @Calinou I just got copy as HTML from terminal ;D

[akien-mga]

vulkan-validation-layers this package doesnt exist.

Fuzzy search is your friend :) On Ubuntu it's https://launchpad.net/ubuntu/+source/vulkan-validationlayers

But that only solves the first 3 errors (should be info messages really), the last one is the main issue: your GPU doesn't support Vulkan with the currently installed driver. What GPU is it?

[nonunknown]

Intel Graphics 3000 HD Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz

[akien-mga]

Mesa on Linux provides Vulkan support for Intel Gen 8+: https://en.wikipedia.org/wiki/Mesa_(computer_graphics)#Table_of_Rendering_APIs

Intel Graphics HD 3000 is Gen 6, Sandy Bridge, so you're out of luck.

Not better on Windows as Intel provides Vulkan dirvers for Gen 9+ only: https://www.intel.com/content/www/us/en/support/articles/000005524/graphics.html

[akien-mga]

BTW, it would be great if you can test the next nightly builds (tomorrow probably) to confirm that #40354 works (it won't make Godot work for you, but it should show an error instead of crashing).

[nonunknown]

@akien-mga The test you told me to do:

[Calinou]

Speaking of which, the error message should be modified to specify which Vulkan version is required (1.0, 1.1, 1.2, …).
