{{outdated|Vulkan layers are enabled by default since we merged {{pull|196310}}. However, this is a good example on how to properly override mesa's package attributes.}}
Vulkan Layers are not enabled by default in [https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/mesa/default.nix Nixpkgs]. You can override the existing Mesa packages and specify them in <code>config.hardware.opengl</code>.

In case you wonder where does <code>["auto"]</code> in mesa's attributes lead you, this might be another way to see them (for 22.3.0[https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-22.3.0/meson.build]):
