Native Wayland gaming with Wine on NixOS

I'm a fan of gaming - my main game is Overwatch. Until this week I've been using xwayland or gamescope to run Wine games which comes with downsides. Xwayland's window management can be buggy - in Gnome I can end up unable to switch back to a game window. Gamescope has some latency and visual artifact issues in my preferred window manager.

But now with the Wine 10 release candidates you can run Wine in native Wayland mode without any special registry settings or anything. And it works very well as far as I can tell! I went through the trouble of figuring out how to get Wine 10 set up on NixOS so I thought I would share.

Wine 10 is currently available in nixos-unstable. The simplest way I've found to get it working for games is to use Lutris, and to install both Lutris and Wine from unstable. To get a complete Wine setup for Lutris use wineWowPackages - for example wineWowPackages.stagingFull. The Full variant includes wine-mono which you'll probably want, and the staging pac

gnome-keyring as ssh agent in lightweight window manager

It took me some time to work out how to get my ssh agent set up in Niri so I though I would share what I did. I'm using NixOS and Home Manager. I put this in my Home Manager config:

 nix
    
services.gnome-keyring = {
  enable = true;
  components = [ "pkcs11" "secrets" "ssh" ];
};
home.sessionVariables.SSH_AUTH_SOCK = "$XDG_RUNTIME_DIR/keyring/ssh";

  

I'm using GDM according to NixOS' default configuration which I think runs gnome-keyring (I thought I saw it in the process list before I set up the user unit), and I think that configuration is automatically unlocking gnome-keyring when I log in via PAM integration. But apparently I need to run gnome-keyring again in my window manager session. Home Manager's services.gnome-keyring adds a systemd user unit that does that.
