[robinmoussu]

Bevy version

Current master (f547885).

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`:

[karroffel]

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.

Duplicate of #96

[rj00a]

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.

[robinmoussu]

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

[razaamir]

Who knows about Asgardia?

vkcube lead me to the right tracks

$ ./vkcube
failed to initialize wayland, falling back to xcb
amdgpu_device_initialize: DRM version is 2.50.0 but this driver is only compatible with 3.x.x.
No Vulkan devices found.

I don't have time right know to look at it, but I will do in the next days.

I get the same result. I'm on a ThinkPad with integrated Intel graphics. vkcube happily spins along without any output.

[rkanati]

@robinmoussu IIRC, vulkan will only work on driver/hardware combinations that support DRI 3. I'm sure there's some technical reason why.

[robinmoussu]

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 ;)

[basile-henry]

@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 😄

[loewenheim]

Thank you, that fixed the problem for me. Although I only had to add the build.rs file; I think the part about patching glslang_validator might be obsolete?

[basile-henry]

Yeah I didn't have to do the glslang_validator patching either. I just assumed that it's only needed for some examples (probably the ones with shaders).

[polendri]

For me (on NixOS), this was resolved by adding the build.rs file as described in the docs for NixOS. My issue was that I had put it in src, not at the root, which meant it wasn't being found.

[robinmoussu]

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.

[Calamari]

Just to understand it correctly, is a vulkan supporting GPU mandatory for using bevy? (So it does not work on a thingpad with onboard intel GPU chip?)

[revdeluxe]

I guess i'm falling back to pygame since Intel HD is not supported by bevy.

[revdeluxe]

Just to understand it correctly, is a vulkan supporting GPU mandatory for using bevy? (So it does not work on a thingpad with onboard intel GPU chip?)

Yes, atleast in alpha.

Here's my Attempt in a iGPU.
SPECS:
CPU: Intel Celeron N3060 2.4GHZ x2
iGPU: Intel HD BSW/400 (For some reason it has vulkan but it's unsable)
RAM: 4GB LPDDR4, 6GB SWAP
ROM: 500GB GPT Toshiba BRFS
DESKTOP: XORG,XFCE
OS: ARCH Linux, 'ArchCraft'

Hypothetically bevy should run fine on Intel Iris iGPU. or on RDNA based iGPU.

[alice-i-cecile]

Reopening this due to a new reproduction.

[Metadorius]

I have the same issue. I was surprised all examples loaded my CPU to the max, seems it's using software renderer:

     Running `target\debug\examples\alien_cake_addict.exe`
2022-07-26T16:00:28.019473Z  INFO bevy_render::renderer: AdapterInfo { name: "Microsoft Basic Render Driver", vendor: 5140, device: 140, device_type: Cpu, backend: Dx12 }

when I tried to change the backend to something non-DX12 the renderer panicked with the error below:

     Running `target\debug\examples\3d_scene.exe`
thread 'main' panicked at 'Unable to find a GPU! Make sure you have installed required drivers!', crates\bevy_render\src\renderer\mod.rs:95:10
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
error: process didn't exit successfully: `target\debug\examples\3d_scene.exe` (exit code: 101)

That's on i5-3320M / HD Graphics 4000.

Hi guys, I'm with the same problem. The xrandr command says that I have 3 xWayland monitors (indeed I have 3 physical screens), I've installed all the mesa drivers and gdm package, and enabled gdm.service, I tried to install vulkan-intel package, but when I do that, the xrandr command shows only 1 monitor with a max resolution of 640x640, so I removed that package.

SPECS:
CPU: 11th Gen Intel(R) Core(TM) i7-1185G7 @ 3.00GHz 1.80 GHz
iGPU: Intel Iris XE
RAM: 16GB DDR4
OS: ARCH Linux (running inside WSL2)

Also, my gdm is working correctly, as show in this image.

[revdeluxe]

Make Bevy self-contained i guess it's far from happening. Atleast add SDL2 support or OpenGL Vulkan is still experimental.

[bengiudice]

If it helps anyone, on Alpine explicitly installing vulkan-loader resolved this.
