Issue description

Related ref: https://github.com/nix-community/home-manager/pull/2968

I can't get syncthingtray with either i3 or sway. It will work if I restart the service with systemctl --user restart syncthingtray after the system started. This is what I have in my home-manager config:

services.syncthing = {
  enable = true;
  tray.enable = true;
};

If I put services.syncthing.tray.command = "syncthingtray --wait", the tray icon will never show up too which is weird.

I bet this is related to #2878, can you confirm?

@exzombie Thanks! I don't have theming issue. And I just tried installing pkgs.gnome-icon-theme and sadly the problem persists.

I have a kludge to fix this:

systemd.user.services.syncthingtray.Service.ExecStart = pkgs.lib.mkForce
    "${pkgs.bash}/bin/bash -c '${pkgs.coreutils}/bin/sleep 5; ${pkgs.syncthingtray-minimal}/bin/syncthingtray'";

I think this is a real issue that needs to be fixed, the problem is going to be getting consensus - particularly with upstream packages - on how to fix it.

If people are relying on kludges, it's not fixed yet.

I've recently played around a bit with HM+systemd tray handling. I don't use syncthing myself, so I can't test this service specifically. But looking at its user unit file, everything looks ok. Are you guys using a separate bar/tray application, or the one built into i3/sway? AFAICT, external tray applications will be started before tray.target and syncthingtray will be started after tray.target, so things should work. The problem is that the WM (and it's builtin bar) is started last, after all the systemd services. In that case, the only proper solution (apart from switching to a separate bar application) is to start your tray apps not as a systemd service, but from the WM.

I have the same issue. I thought it might be related to using a quite old low power computer (Manjaro in Intel NUC 7i3BNH), as it works great on another installation of Manjaro on an up-to-date CPU.

--wait fixes the issue for me, but it seems to be kind of a dirty workaround.

I tried a different hack. I set services.syncthing.tray.enable to false, then then set wayland.windowManager.sway.startup to [{ command = "${pkgs.syncthingtray-minimal}/bin/syncthingtray"; }]; (and similar for i3).

Unfortunately, it does not work, I get the error from swaythingtray that the tray hasn't started yet.

Which isn't really surprising, but thought I should mention it here.
