Segfault on default app on NixOS/NVIDIA GPU. #13753

Open Azercoco opened 3 months ago

Azercoco commented 3 months ago

Bevy version

bevy = "0.13.2"

[Optional] Relevant system information

What you did

I did try to launch the default app :

use bevy::{app::App, DefaultPlugins};

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .run();
}

using the nix shell

{ pkgs ? import <nixpkgs> { } }:

with pkgs;

mkShell rec {
  nativeBuildInputs = [
    pkg-config
    cargo
    rustc
    rustfmt
  ];
  buildInputs = [
    udev
    alsa-lib
    vulkan-loader
    xorg.libX11
    xorg.libXcursor
    xorg.libXi
    xorg.libXrandr # To use the x11 feature
    libxkbcommon
    wayland # To use the wayland feature
  ];
  LD_LIBRARY_PATH = lib.makeLibraryPath buildInputs;
  RUST_SRC_PATH = "${pkgs.rust.packages.stable.rustPlatform.rustLibSrc}";
}

nix-shell
cargo run

What went wrong

The application compiles without issue but when I launches it, the window open for a couple of second before encountering a segfault. I am not sure if the issue is Nix-OS related or NVIDIA related. The lack of useful log or similar issues make it very hard to troubleshoot.

Are you able to run with MinimalPlugins? The next step is to try and dissect what plugins are causing this: my guess is either rendering or perhaps even the gathering of the system info itself.

Azercoco commented 3 months ago

No issue with MinimalPlugins. The issue really seems to come from the Window.

This happens to me as well, since I switched to Wayland.

The log is not very useful ``` -> RUST_BACKTRACE=full cargo run Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.19s Running `target/debug/app` 2024-06-13T17:25:31.242649Z WARN log: error setting XSETTINGS; Xft options won't reload automatically 2024-06-13T17:25:31.247122Z INFO bevy_winit::system: Creating new window "App" (0v1) 2024-06-13T17:25:31.247453Z INFO log: Guessed window scale factor: 1 libEGL warning: egl: failed to create dri2 screen 2024-06-13T17:25:31.375265Z INFO bevy_render::renderer: AdapterInfo { name: "NVIDIA GeForce GTX 1070", vendor: 4318, device: 7041, device_type: DiscreteGpu, driver: "NVIDIA", driver_info: "555.52.04", backend: Vulkan } 2024-06-13T17:25:32.013630Z INFO bevy_diagnostic::system_information_diagnostics_plugin::internal: SystemInfo { os: "Linux 24.05 NixOS", kernel: "6.6.32", cpu: "Intel(R) Core(TM) i7-6850K CPU @ 3.60GHz", core_count: "6", memory: "94.2 GiB" } 2024-06-13T17:25:32.172836Z WARN bevy_render::view::window: Couldn't get swap chain texture. This often happens with the Nvidia 550 driver. It can be safely ignored. zsh: segmentation fault (core dumped) RUST_BACKTRACE=full cargo run ```

After trying it out multiple times I managed to get a panic with a backtrace once, and a few times it seemed to start fine... I will try to look into this some more...

I'm pretty sure this is either an issue with Wayland or with the 555 nvidia driver - I didn't really make any other changes to my system since it worked.

Edit: I quickly reverted back to X11 using the 555 driver - no problems there, so it really seems to be a Wayland issue

MonaMayrhofer commented 3 months ago

I just noticed, the app doesn't immediately crash. It starts up just fine and even does stuff and is interactive - sometimes it runs for up to 3 seconds - then segfaults

Oh my god...

Well, for me at least adding the "wayland" feature to bevy fixed the crash.

I suspect without it bevy was run with xwayland and then weirdness ensued... I will investigate further tho until I am 100% sure.

Edit: Yup!

without having features = ["wayland"] the app silently runs under xwayland and crashes after a few seconds. When adding features = ["wayland"] the app runs natively on wayland and works just fine.

So i guess the real bug here is that bevy crashes on xwayland - otherwise everything works as expected. I wonder if we should detect whether or not we are running in wayland and then print a warning if the app was built without the wayland feature

So this issue is really just #8788 with added segfault spicyness

And when #10792 is merged this shouldn't be a big problem anymore...

This also fixed the problem for me. Thanks.
