AdapterNotFound on Pixel::new

[harrysarson]

Hi, I am trying to run the minimal-winit example (on git master) and I get

Error: AdapterNotFound

I looked at #83 and #29 and tried WINIT_UNIX_BACKEND=x11 cargo run but got the same error. Installing xorg-server and libx11 but neither helped.

Your host needs to support Vulkan, and you may be missing drivers, or running on a very old driver. Support for OpenGL is currently a work in progress.

Hi thanks the makes sense :). I will look into my drivers re Vulcan. Is there a way of getting more debugging info out of pixel or winit?

[parasyte]

Yes! The examples use a crate called env_logger which allows you to control debug logs through the RUST_LOG environment variable. You can read more about it in the linked docs.

The examples also have a feature set on the log crate that limits the log level in release builds. So for debug logs, you should build the debug profile. Here’s a simple example:

$ RUST_LOG=trace cargo run --package=invaders

Thanks, I will give that a try next time I have some time. I will close for now and see if I can get it work.

Thanks for you help

In case anyone else ends up here: As per the arch vulkan docs I installed vulkan-intel and the example now runs. 👍
