Launching editor fails with nix shell on arch linux

[NandorKovacs]

This is probably an error on my end.

I got the editor working, however not using the provided shell.nix. I was happy i didn't have to search what the package names on arch are, and just tried using the provided nix shell.

However, when using the provided shell.nix, launching the editor with RUST_BACKTRACE=full cargo run --package fyroxed results in the following stack trace:

thread 'main' panicked at editor-standalone/src/main.rs:56:52:

I am unsure what i am doing wrong. I tested my nix setup, and packages do seem to work. I am however using arch linux, maybe it would work on NixOS?

[mrDIMAS]

This error usually comes from alsa, you need to setup it properly. I'm not a Linux user, so I can only google for solutions.

Edit: no, it is not.

[mrDIMAS]

I looked at the code where this error comes from and it seems that I was wrong about alsa. It actually comes from X11 (which is used by default), so you might need to switch your OS to it and the engine should work fine.

[NandorKovacs]

interesting, i use alsa as well as x11.

it has probably something to do with my nix configuration, as everything works without the nix shell.

thanks for the response though! if you prefer to, you can close the issue, i mostly opened it so that you know that something might be up with the provided shell.nix

[mrDIMAS]

Try using Wayland, it might fix the issue. I remember someone in Discord server mentioned that switching to Wayland helps.
