clock example fails on FreeBSD: Error: GraphicsCreationFailed(GraphicsAdapterNotFound)

[yurivict]

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

$ cargo run --package clock
    Finished dev [unoptimized + debuginfo] target(s) in 0.26s
     Running `/tmp/iced/target/debug/clock`
Error: GraphicsCreationFailed(GraphicsAdapterNotFound)

What is the expected behavior?

n/a

Version

master

Operative System

Linux

Do you have any log output?

No response

You could try building with the glow feature flag to use the glow backend instead of wgpu. (Though it has some limitations currently.)

Do you have a driver with that supports Vulkan?

[ids1024]

The clock example seem to run for me on FreeBSD without any changes or feature flags (AMD Renoir integrated graphics, drm-kmod/amdgpu installed, on either X or Wayland).

[yurivict]

My GPU is NVidia. Do I have to install some package for this?

[ids1024]

I don't think it should require anything specific other than installing and enabling the drivers that would be needed for accelerated graphics in any other software: https://docs.freebsd.org/en/books/handbook/x11/#x-config-video-cards

glxinfo from the mesa-demos package and vulkaninfo from vulkan-tools will show what if any versions of OpenGL and Vulkan are available with currently installed drivers.

I have a functional OpenGL installation but the clock example fails with the error from my first message.

[ids1024]

What about Vulkan? Wgpu defaults to that, not sure if it should automatically fallback. WGPU_BACKEND=gl should get it to run with OpenGL instead.

[yurivict]

Same error with WGPU_BACKEND=gl

[ids1024]

Hm, not sure why it's working on my FreeBSD install but not yours. I would look at glxinfo and vulkaninfo to see what OpenGL / OpenGL ES / Vulkan versions it advertises support for. (Though I don't think that should be a problem unless it's a fairly old GPU.)

cargo run -p clock --features iced/glow will make it run with the Glow backend instead of Wgpu which may work. (But will fail to compile for examples using images, which aren't currently supported by the Glow backend.)

[yurivict]

cargo run -p clock --features iced/glow works.

Are your vulkan libraries located in a non-standard path?

I had the same problem for both glow and vulkan/wgpu in NixOS. I solved it by specifying the path to the libraries:

LD_LIBRARY_PATH="/run/opengl-driver/lib/:${pkgs.libGL}/lib/:${pkgs.libGLU}/lib/:${pkgs.vulkan-headers}:${pkgs.vulkan-loader}/lib/";

Of course you have to adapt the paths.

According to unrelated bug you have GeForce GT 610 which is limited to legacy 390 series of NVIDIA driver. However, NVIDIA didn't include Vulkan driver in FreeBSD version back then:

mesa-dri >= 21.3.7 package includes lavapipe, so WGPU_BACKEND=vulkan (default) should fall back to software rendering unless explicitly ignored due to performance/compatibility.
