bevy: thread 'main' panicked at 'Unable to find a GPU! Make sure you have installed required drivers!'

Bevy version

Current master (f54788527be49c445ec6e1c8831496a821d4fcc2).

Operating system & version

Archlinux, with Xorg

What you did

I tried to run cargo run --example $EXAMPLE. All but ecs_guide, headless, headless_wasm, hello_word, and startup_system failed with the following error:

thread 'main' panicked at 'Unable to find a GPU! Make sure you have installed required drivers!', crates/bevy_wgpu/src/wgpu_renderer.rs:37:14
``

**Additional information**

As far as I can tell, my GPU drivers should work but I don't know how to check it! I'm using a R9 280X as reported by `lspci`:

@rj00a I’m also on NixOS and was hitting this issue. I managed to make the examples work by following https://github.com/bevyengine/bevy/blob/master/docs/linux_dependencies.md#nixos 😄

I’m closing this issue since my GPU doesn’t support vulkan. For future readers, they where many useful comments regarding workarounds for people having a compatible GPU in this thread that you may find useful.

I admit that I assumed that my GPU would be able to run vulkan. If it doesn’t this just give me one more reason to upgrade 😉

robinmoussu on Nov 11, 2020

I’m surprised. I followed the arch wiki, and I have both amdvlk and vulkan-radeon installed, and as you can see, it should be working.

$ ls /usr/share/vulkan/icd.d/
amd_icd32.json  amd_icd64.json  radeon_icd.x86_64.json

I’m running into this issue despite being able to execute vkcube successfully. As far as I can tell, my vulkan drivers should be set up correctly. I’m using NixOS unstable with Xorg.

rj00a on Nov 8, 2020

The message is not super clear, but to use the default bevy_wgpu your system needs to have Vulkan drivers installed which doesn’t seem to be the case for your system. After installing drivers it should work.
