Bevy is data-driven engine written in Rust. The repository of Bevy contains several examples which can be started by a command like:

git clone --depth 1 https://github.com/bevyengine/bevy.git
cd bevy
cargo run --example alien_cake_addict

Users of openSUSe might experience following error:

hread 'main' panicked at 'Unable to find a GPU! Make sure you have installed required drivers! For extra information, see: https://github.com/bevyengine/bevy/blob/latest/docs/linux_dependencies.md', crates/bevy_render/src/renderer/mod.rs:121:10
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

The problem is caused by missing Vulkan libraries in the system. This can be confirmed by running vkcube which may result in the following error:

vkEnumerateInstanceExtensionProperties failed to find the VK_KHR_surface extension.

Do you have a compatible Vulkan installable client driver (ICD) installed?
Please look at the Getting Started guide for additional information.

Check which graphic card is installed in the system:

sudo lspci -nnk | grep -A3 VGA

Which might result in a message like this:

00:02.0 VGA compatible controller [0300]: Intel Corporation CometLake-U GT2

With this knowledge, it’s clear that library Vulkan Intel is missing and can be installed simply by:

sudo zupper install libvulkan_intel

Application vkcube should work after this change.
