Linux Port – Feedback, Known Issues, and FAQ

It sounds really raw, digitised and like un-mixed compared to how I hear it

 

Yeah, sorry for mistake

Exactly, I can even hear the pitch change going in "steps" rather than being smooth.

It's better when using the orbit camera behind the car, but the closer to the engine, the worse it gets.

 

I figured as a new owner and NixOS user, I'd include a sort of minimal working configuration since I haven't seen anything else definitive in this thread in that regard. Apologies if this is a bad place to post this, but I figured it might be one of the first places people end up looking.

I chose to use the nix-ld approach to get this running, and ended up with:

Code:

  programs.nix-ld = {
    enable = true;
    libraries = [
      pkgs.alsa-lib
      pkgs.at-spi2-core
      pkgs.cairo
      pkgs.cups
      pkgs.dbus
      pkgs.fontconfig
      pkgs.freetype
      pkgs.glib
      pkgs.libgbm
      pkgs.libx11
      pkgs.libxcb
      pkgs.libxext
      pkgs.libxfixes
      pkgs.libxkbcommon
      pkgs.libxrandr
      pkgs.nspr
      pkgs.nss
      pkgs.pango
      pkgs.vulkan-loader
      pkgs.xorg.libXcomposite
      pkgs.xorg.libXdamage
    ];
  };

And then it runs from the command line with:

Code:

SDL_VIDEODRIVER=x11 ~/.local/share/Steam/steamapps/common/BeamNG.drive/BinLinux/BeamNG.drive.x64

I'm definitely open to suggestions though if there is a better way of doing this under NixOS. Already crashed my limo a few times!

 

I use nixos and nix-ld, too. But I can't get it running on kde plasma wayland with `SDL_VIDEODRIVER=wayland`. And it gives the output below.

```
Shutdown handler: initialize.
>>>> [CURRENT_CONFIGURATION=SHIPPING=BNG_SHIPPING] <<<<
[2025-10-02 16:54:31.180] [error] [:-1] wayland not available
Failed to init bngenv: Failed to init app instance framework
Shutdown handler: cleanup.
```

May I ask have you tried wayland and do you get the same error?

 

I've run into a rather dangerous (for both humans and FFB motors) situation when pausing the game during a challenge: The active constant force FFB effect will not be cancelled and so the last commanded motor torque will be sustained until either the player resumes, or exits the scenario, or if restarting the scenario effects are reinitialised. In the meantime the user will potentially have to resist the motor applying a lot of torque (especially a problem on high power wheelbases) otherwise the wheel will immediately and rapidly accelerate. High motor output sustained like this can be (nearly) impossible to hold with one hand for an extended duration (the other hand reached over to the keyboard to hit the escape key) and for extremely powerful wheelbases can cause injury to the hand/arm still on the wheel. If the user lets go in this situation the wheelbase will accelerate and now you have a wheel spinning at max RPM, another potentially injurious situation. This is also dangerous for wheelbase motors which may be producing output near their peak and way above their rated output which may cause overheating and damage to the coils or permanent magnets.

This feels like a bug as pretty much every other game will cancel all FFB effects when in a pause menu state like this.

Steps to reproduce

1. Start any challenge scenario
2. Start driving
3. Hit the Escape key
4. Feel the force

On NixOS I have the following derivation which produces a wrapper script that I can use to start Beamng via my Steam library. Ensure the resulting script is on your PATH and then set the launch options line to:

Code:

launch-beamng %command

It's also compatible with using other wrapper programs such as gamemoderun and mangohud:

Code:

launch-beamng gamemoderun mangohud %command%

Code:

{ pkgs, ... }:
let
  libraryPath = pkgs.lib.makeLibraryPath [
    pkgs.fontconfig
    pkgs.freetype
    pkgs.glib
    pkgs.nss
    pkgs.nspr
    pkgs.dbus
    pkgs.atk
    pkgs.cups
    pkgs.libdrm
    pkgs.xorg.libX11
    pkgs.xorg.libXcomposite
    pkgs.xorg.libXdamage
    pkgs.xorg.libXext
    pkgs.xorg.libXfixes
    pkgs.xorg.libXrandr
    pkgs.libgbm
    pkgs.xorg.libxcb
    pkgs.libxkbcommon
    pkgs.pango
    pkgs.cairo
    pkgs.alsa-lib

    pkgs.vulkan-loader
    pkgs.libglvnd
  ];
in
pkgs.writeScriptBin "launch-beamng" ''
  #!/usr/bin/env ${pkgs.lib.getExe pkgs.bash}

  set -euo pipefail

  export LD_LIBRARY_PATH="${libraryPath}:$LD_LIBRARY_PATH"

  cmd=$(printf '%s ' "$@")
  cmd=$(sed -E 's#/[^ ]*/steam-launch-wrapper -- .* ([^ ]*/proton waitforexitandrun)##' <<< "$cmd")
  cmd=$(sed -E 's#BeamNG\.drive\.exe#BinLinux/BeamNG.drive.x64#' <<< "$cmd")

  $cmd

I'm having an issue that manifested out of nowhere, after smooth playing for days. Here's the log, I hope it helps. Attached is a screenshot depicting what happens.

Error is triggered by me making any change to a vehicle. Any. Even license plates design triggers it. Car keeps floating above the ground and locks up completely, no ignition, no horn, no lights, no nothing. I can spawn another car and drive it fine, until I try to modify it also, then the same thing happens, but there's a 50/50 change the second car's meshes get absolutely messed up. Can't remove any car, and more inputs crash the game, complete with the crash report window.

Specs attached in my fastfetch screencap. Running the binary via Steam with these launch properties: mangohud SDL_VIDEODRIVER=wayland ./BinLinux/BeamNG.drive.x64 %command%

What I tried:

• Clearing cache (by deleting "temp" folder): Error persists.
• Renaming mod folder so no mod loads: No error.
• Launching the binary in safe mode: No error.

Haven't tried the Proton version though.

UPDATE & SOLVED (?): I deleted the latest mods I've downloaded: Isola Rocciosa and Tyres Thermal and Wear. Error stopped.

 

in case u experience random performance lags liek 1-2 second slowdowns once per while do a

Code:

taskset 0xfff0

before game executable
it will make game not use core 1-4 that is shared between ui and background apps by default on linux

 

Thanks for fixing the dpad on Logitech wheels!
