Not all apps support running natively on Wayland. To work around this, ~~XWayland~~ should be enabled. {{Note|Enabling XWayland varies slightly from Compositor to Compositor, and may already be enabled. Consult your Compositor's documentation and/or nix file for how to enable}}

=== Electron and Chromium ===

Ozone Wayland (which uses Wayland native instead of Xwayland) support in [[Chromium]] and [[Electron]] based applications can be enabled by setting the environment variable "<code>NIXOS_OZONE_WL</code>" with <code>NIXOS_OZONE_WL=1</code> ''(also see [https://github.com/NixOS/nixpkgs/commit/b2eb5f62a7fd94ab58acafec9f64e54f97c508a6 commit])''

As of NixOS 25.05 ("Warbler"), if <code>XDG_SESSION_TYPE</code> is unset or set to "wayland", [https://issues.chromium.org/issues/40083534#comment599 chromium and electron apps will default to wayland native]. This ignores the <code>DISPLAY</code> environment variable.

As of NixOS 22.05 ("~~Quokka~~"), ~~you can enable Ozone Wayland support in~~ [~~[Chromium]]~~ and ~~[[Electron~~]~~] based applications by setting~~ the ~~environment variable~~ <code>~~NIXOS_OZONE_WL=1~~</code>. ~~For example, in a {{ic|configuration.nix}}:~~

~~<syntaxhighlight lang~~=~~"nix">~~

==== Declaratively (permanent) ====

environment.sessionVariables.NIXOS_OZONE_WL = "1";

===== NixOS =====

{{File|3=environment.sessionVariables.NIXOS_OZONE_WL = "1";|name=/etc/nixos/configuration.nix|lang=nix}}

==== Imperatively (each time an application is launched) ====

Example: to launch <code>code</code> ''({{Nixpkg|pkgs/applications/editors/vscode/vscode.nix|vscode}})''<syntaxhighlight lang="console">

NIXOS_OZONE_WL=1 code

</syntaxhighlight>

~~This allows these applications to run without Xwayland.~~
