Intermittent hang on shutdown

Open lostipod opened this issue 1 year ago • 5 comments

Describe the bug Intermittently, when shutting down: Stopping Session 3 of User test ... a bunch of OKs then A stop job is running for Session 3 of User test (1s / 1 min 30s) It then counts up to 90 seconds then finally shuts down.

To Reproduce Shutdown desktop, via Cosmic terminal or Cosmic desktop. Happens intermittently.

Expected behavior No hang, a bunch of OKs and shuts down in a couple of seconds.

Screenshots N/A

Desktop (please complete the following information):

  • Arch with hardened kernel
  • no other DEs installed

Additional context

  • has happened since first using Cosmic, around Alpha 3 and has continued up until now (Alpha 6)
  • Not certain, but seems to be related to Flatpak or perhaps not Flatpak generally but only the Firefox Flatpak
  • most noticed (perhaps only noticed) when the Firefox Flatpak was opened during the Cosmic session but intermittently
  • due to hardened kernel have to use bubblewrap-suid package instead of bubblewrap package for Flatpak
  • packages xdg-desktop-portal and xdg-desktop-portal-cosmic are installed

Attached Logs

  • see attached log on April 12 at 11:31 AM (and add 90 seconds of padding both before and after)
  • systemd.log_level=debug
  • used Gemini 2.5 Pro (experimental) to analyze logs but the model reported " the specific process causing the deadlock isn't explicitly named in this log. Systemd reports the timeout occurring for the overall user manager service because it couldn't get everything under its control to stop cleanly."

I have a similar issue on nixos. I've attached my log (journalctl -b -1) showing that both cosmic-settings and notify-rs fail to terminate properly as seen on lines 1871 and 1872. I've also added my nixos config, which is very basic.

I have a similar issue on nixos. I've attached my log (journalctl -b -1) showing that both cosmic-settings and notify-rs fail to terminate properly as seen on lines 1871 and 1872. I've also added my nixos config, which is very basic.

What I wanted to try but is a bit unprecise: Fresh install of nixOS directly with COSMIC and see if that fixes the issue and second experiment use unstable but that's very much not what I actually want to run.

But first I am going to try to run COSMIC with something like

environment.sessionVariables = {
  RUST_LOG = "cosmic_settings=trace,iced=trace";  # Target specific crates if needed
};

and see if this digs something up and also try to find out whether I can override the COSMIC packages to use nixpkgs-unstable instead.

Confirming this issue on NixOS

I'm experiencing the exact same issue on a different setup, which might help narrow down the cause:

System Info:

  • OS: NixOS 25.05 unstable (Warbler)
  • Kernel: 6.17.5
  • Cosmic Version: 1.0.0-alpha.7
  • GPU: AMD Renoir (Radeon Vega Series / Radeon Vega Mobile Series)

Key Differences from OP:

  • Happens almost every shutdown (not just intermittently)
  • Not using Flatpak - so this doesn't appear to be Flatpak-specific
  • Clean Cosmic-only setup, no other DEs installed

Behavior: Same 90-second timeout with "A stop job is running for Session X of User" message during shutdown.

Logs showing the hang:

nov 01 19:43:24 nixos cosmic-session[1368]: EXITING: received request to terminate
nov 01 19:43:24 nixos cosmic-session[1368]: process 'ProcessKey(2v1)' cancelled
nov 01 19:43:24 nixos systemd[1]: Stopping Session 3 of User huxx...
[90 second gap - no activity from cosmic-session]
nov 01 19:44:54 nixos systemd[1]: Stopped Session 3 of User huxx.

cosmic-session logs "EXITING" but the process doesn't actually exit until systemd kills it after the full timeout period.

Possibly Related Runtime Errors: Throughout the session, cosmic-session repeatedly logs:

  • No such file or directory (os error 2)
  • Failed to watch theme org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.GeoClue2 was not provided by any .service files

This confirms the issue affects multiple distros and isn't Flatpak-specific. Happy to provide additional logs or testing if helpful!

Try installing geoclue2 https://discourse.nixos.org/t/timeout-on-shutdown-with-cosmic-due-to-session-3-scope/70326/9?u=daemonfire

This will be fixed with 25.11 and is already fixed on unstable. I fixed it manually on my stable version.
