 ## Enabling GNOME Flashback {#sec-gnome-enable-flashback}
 
 GNOME Flashback provides a desktop environment based on the classic GNOME 2 architecture. You can enable the default GNOME Flashback session, which uses the Metacity window manager, with:
 
-```
-services.xserver.desktopManager.gnome.flashback.enableMetacity = true;
+```nix
+{
+  services.xserver.desktopManager.gnome.flashback.enableMetacity = true;
+}
 ```
 
 It is also possible to create custom sessions that replace Metacity with a different window manager using [](#opt-services.xserver.desktopManager.gnome.flashback.customSessions).
 
 The following example uses `xmonad` window manager:
 
-```
-services.xserver.desktopManager.gnome.flashback.customSessions = [
-  {
-    wmName = "xmonad";
-    wmLabel = "XMonad";
-    wmCommand = "${pkgs.haskellPackages.xmonad}/bin/xmonad";
-    enableGnomePanel = false;
-  }
-];
+```nix
