Qt plugin issue when using steam-run #73414

Just recently switched to NixOS, so I am pretty new to this. After posting this issue on the nixos-discourse, I was asked to post this issue here.

Describe the bug
When I use steam-run to start a specific program I get the following issue:

This application failed to start because it could not find or load the Qt platform plugin "xcb".

Available platform plugins are: linuxfb, minimal, offscreen, xcb.

Reinstalling the application may fix this problem.

That program is not freely available. The program in question is RPG Maker MV.

This is the only program that I could not get working on my NixOS setup. So any help would be appreciated.

To Reproduce
Steps to reproduce the behavior:

  1. Use run-steam to start the program.

Expected behavior
The program starts.

I can provide some, if needed. But I don't think they show anything not already told.

Additional context
I already tried starting it with normal steam, which does not work due to non-standard locations for libraries. When I run the program inside an FHS environment I get the same error.


  • system: "x86_64-linux"

  • multi-user?: yes
  • sandbox: yes
  • version: nix-env (Nix) 2.3
  • nixpkgs: /nix/var/nix/profiles/per-user/root/channels/nixos

Got it working, by changing up the RPG Maker file.

It just had LD_LIBRARY_PATH=$dirname instead of LD_LIBRARY_PATH=$dirname:$LD_LIBRARY_PATH.
