• Bevy 0.5.0
• Alter Linux (based on Arch Linux)

Hey everyone! I need help.

When I run Bevy with DefaultPlugins, like this:

use bevy::prelude::*;
fn main() {
  App::build().add_plugins(DefaultPlugins).run();
}

I got this error:

thread 'main' panicked at 'Unable to find a GPU! Make sure you have installed required drivers!', 
/home/firefly/.cargo/registry/src/github.com-1ecc6299db9ec823/bevy_wgpu-0.5.0/src/wgpu_renderer.rs:47:14
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

What should I do?

What GPU do you have and what drivers have you installed for it?

[tsklxiv]

I have an Intel Mesa GPU and I have installed some Vulkan drivers: The Intel Mesa Vulkan driver (vulkan-intel), Mesa's Vulkan layer (vulkan-mesa-layer) and vulkan-devel.

Can you run any of the wgpu examples? https://github.com/gfx-rs/wgpu

I have the same problem, running on Arch Linux and Bevy 0.5.0.

I have an older graphics card (NVIDIA Corporation GT218M [GeForce 310M]) that uses the NVIDIA 340xx drivers, and I have vulkan-intel installed.

I tried to run the hello wgpu example per @Ixentus 's suggestion, and it indeed fails:

Is there some configuration I can tweak? Or is this card too old to ever run Bevy/wgpu?

[bjorn3]

According to https://wiki.debian.org/NvidiaGraphicsDrivers the proprietary nvidia 340 series graphics drivers doesn't support Vulkan. Bevy will likely update to wgpu 0.10 once the 2021 edition is released, which has OpenGL support. We are waiting for the 2021 edition as wgpu 0.10 requires the v2 dependency resolver of cargo, which will be the default in the 2021 edition.

Thanks for the fast answer and for the reference! I guess I'll have to wait and use a newer machine until then. =)
