Nixpkgs: Restarts of accountservice crashes gnome3

[etu]

Issue description

If account-daemon restarts in a gnome3 session it totally breaks and becomes unusable.

What happens for me if account-daemon restarts is that I see the screen flash like the login animation from gdm. All programs are still up. But the mouse is frozen and I can't even switch to a tty with my keyboard. The only thing that it actually responds to seems to be Ctrl+Alt+Delete which triggers a reboot. And this indicates that I'm actually in a tty but I see an image of my gnome-session.

This is a problem when doing nixos-rebuild switch etc.

I had a proposed fix in https://github.com/NixOS/nixpkgs/pull/45936 but dropped my branch because I was unsure if that fixed the issue, but I'm having that overriden in my personal config here: https://github.com/etu/nixconfig/commit/052b9d67adc4581532e7805b78c2da1fd492c3ff

And it's much better while doing nixos-rebuild switch or nixos-rebuild test or so than it was before.

Steps to reproduce

This can be tested by just doing a sudo systemctl restart accounts-daemon.service.

This is also breaking my ui whenever I try activate a configuration.

Filed bug upstream: https://gitlab.freedesktop.org/accountsservice/accountsservice/issues/55

[thefloweringash]

For those looking to work around this, it should be sufficient to remove any services.xserver.displayManager.gdm.autoLogin config. (Untested).

[worldofpeace]

This still an issue @etu?

[etu]

@worldofpeace oh, sorry. I've forgotten about this issue and stopped running gnome like 8 months ago. So I have no idea :D

[worldofpeace]

I'm able to confirm that when using autoLogin in GDM that restarting the accounts-daemon does crash the session. And systemd.services.accounts-daemon.restartIfChanged = false; isn't a sufficient workaround.

[jameysharp]

I'm seeing a very similar stack trace from gnome-shell in my user session after a system.autoUpgrade-triggered nixos-rebuild switch. I'm not using GDM auto-login.

I don't have debug symbols but here's the stack trace from coredumpctl debug. Note that the top of the stack is still in on_user_changed in libaccountsservice. When I went looking at the source for these functions, the only thing which made sense was that act_user_get_user_name returned NULL, which led me to the upstream bug and then to here.

Had the exact same issue today. my backtrace is identical to that of @jameysharp

[worldofpeace]

This needs an upstream fix as reported in https://gitlab.freedesktop.org/accountsservice/accountsservice/issues/55. This is very confirmed.

[jameysharp]

I've been testing the systemd.services.accounts-daemon.restartIfChanged = false; workaround on one laptop and not on another.

On the laptop without the workaround, upgrading from 19.09.1160.a22b018900 to 19.09.1172.2d896998dc9 caused gnome-shell to crash.

On the laptop with the workaround, upgrading to that version from an older version (19.09.1149.107e2b7b29f) did not lead to a gnome-shell crash.

@worldofpeace, why did you say this is not a sufficient workaround? It's kind of a pain to test so I can easily believe I'm missing something.

Is it important to restart accounts-daemon on upgrade? I assume no other distro has reported this bug or there'd hopefully be more activity in the upstream bug report. Are other distros just not restarting it on upgrade for some reason, maybe?

Perhaps it's that… because NixOS treats accounts-daemon as changed if any of its transitive dependencies change, we upgrade+restart it a lot more frequently than anybody else does? Maybe nobody else is noticing because accounts-daemon changes rarely and other distros aren't triggering the crash often enough to annoy people into investigating?

I'm also seeing this crash and UI hang during nixos-rebuild switch. I am not using gdm at all (I'm using sddm). I'm able to recover the hung session if I can get to a terminal by running gnome-shell --replace &. I left a note in the upstream bug with G_MESSAGES_DEBUG=all log output.

Still happens on NixOS 20.03 because the fix was never ported. Here is my backtrace from gdm, which seems to be exactly the same as reported earlier in this thread.
