I received the `Unable to find GPU` error, but I got it to render by using this package. Not 100% sure if a better option exists.

Installing Linux dependencies
This page lists the required dependencies to build a Bevy project on your Linux machine.
If you don't see your distro present in the list, feel free to add the instructions in this document.
Ubuntu 20.04
sudo apt-get install pkg-config libx11-dev libasound2-dev libudev-dev
Depending on your graphics card, you may have to install one of the following:
vulkan-radeon
, vulkan-intel
, or mesa-vulkan-drivers
If you want to enable fast compiles
sudo apt-get install clang
Windows Subsystem for Linux (WSL 2)
Graphics and audio need to be configured for them to work with WSL 2 backend. Please see the ubuntu WSL documentation on how to set up graphics and audio.
Fedora 33
sudo dnf install gcc-c++ libX11-devel alsa-lib-devel systemd-devel
Arch / Manjaro
sudo pacman -S libx11 pkgconf alsa-lib
Solus
sudo eopkg install pkg-config libx11-devel g++ alsa-lib-devel
Void
sudo xbps-install -S pkgconf alsa-lib-devel libX11-devel eudev-libudev-devel
NixOS
Add a build.rs
file to your project containing:
# build.rs
fn main() {
if cfg!(target_os = "linux") {
println!("cargo:rustc-link-lib=vulkan");
}
}
These packages provide the dependencies required to run a bevy project. They can be installed globally or via nix-shell. Based on your global configuration it also might be necessary to allow unfree packages:
export NIXPKGS_ALLOW_UNFREE=1 # needed for lutris
nix-shell -p cargo pkgconfig udev lutris alsaLib x11 xorg.libXcursor xorg.libXrandr xorg.libXi vulkan-tools vulkan-headers vulkan-loader vulkan-validation-layers
Alternatively, you can define shell.nix
containing:
# shell.nix
{ pkgs ? import <nixpkgs> { } }:
with pkgs;
mkShell {
buildInputs = [
cargo
pkgconfig udev alsaLib lutris
x11 xorg.libXcursor xorg.libXrandr xorg.libXi
vulkan-tools vulkan-headers vulkan-loader vulkan-validation-layers
];
}
And enter it by just running nix-shell
.
You should be able compile bevy programms using cargo
within this nix-shell.
