[SOLVED] Can't logon: "Could not get properties: Unknown objet"

TL;DR
When trying to logon at machine startup, via CLI, I get the error:

Could not get properties: Unknown objet '/org/freedesktop/login1/user/self'

Then the screen is cleared and the logon prompt shows again.

Context
The issue first appeared after a full system upgrade (pacman -Syu) and a reboot.

Details
Using a bootable USB stick, I was able to mount and arch-chroot into my "/" and "/home" and get the following from the journal, at the time of failed logons. The only thing that seemed out of the ordinary is:

Sep 16 13:35:04 foo-hostname dbus-broker-launch[1105]: Service file '/usr/share/dbus-1/services/org.xfce.xfce4-notifyd.Notifyd.service' is not named after the D-Bus name 'org.xfce.Notifyd'.
Sep 16 13:35:04 foo-hostname dbus-broker-launch[1105]: Service file '/usr/share/dbus-1/services/org.xfce.xfce4-notifyd.Notifications.service' is not named after the D-Bus name 'org.freedesktop.Notifications'.
Sep 16 13:35:04 foo-hostname dbus-broker-launch[1105]: Service file '/usr/share/dbus-1/services/org.xfce.Tumbler.Thumbnailer1.service' is not named after the D-Bus name 'org.freedesktop.thumbnails.Thumbnailer1'.
Sep 16 13:35:04 foo-hostname dbus-broker-launch[1105]: Service file '/usr/share/dbus-1/services/org.xfce.Tumbler.Manager1.service' is not named after the D-Bus name 'org.freedesktop.thumbnails.Manager1'.
Sep 16 13:35:04 foo-hostname dbus-broker-launch[1105]: Service file '/usr/share/dbus-1/services/org.xfce.xfce4-notifyd.Notifyd.service' is not named after the D-Bus name 'org.xfce.Notifyd'.
Sep 16 13:35:04 foo-hostname dbus-broker-launch[1105]: Service file '/usr/share/dbus-1/services/org.xfce.Thunar.FileManager1.service' is not named after the D-Bus name 'org.freedesktop.FileManager1'.

I have also used arch-chroot to, using pacman, re-install some at first, then all of the existing package on my setup, but it did not change a thing.

Appart from that, I have tried:
- Changing TTY (CTRL+ALT+Fx) but other TTY show the same issue
- Use another user (e.g. root, instead of my default user) but they show the same issue
- re-installing all the pacman known packages (hundreds of them), it did not help
- remove the lines auto-starting xfce4 from my zshrc, it did not help

Setup
My setup is a vanilla LTS 6.6.51-1-lts arch distrib using xfce as Desktop Environment and Awesome as WindowManager.
The whole setup has been running on a laptop without any major issues for a couple years now, and I do a full system upgrade every week or so.

Any help or idea is more than welcome, I'd rather avoid a full reset as the backup of my home dir would be cumbersome...

There's probably some spurious "exit" call in your shell rc or /etc/profile - but since all users are affected you're likely looking at some global config, except

remove the lines auto-starting xfce4 from my zshrc, it did not help

if all you users use zsh and you've install OMZ. Then it's OMZ.

Re: [SOLVED] Can't logon: "Could not get properties: Unknown objet"

Thanks for your reply seth.

I don't have OMZ installed but I use powerlevel10k which is kinda similar it seems.

I looked into /etc/profile and /etc/profile.d/*, there is no such thing as an exit instruction. All the profiles files and their contents are pretty vanilla. My tinkering of profiles are now dated, made only to my current user's .zshrc, and limited to harmless aliases and PATH additions.
I have tried to switch my user to /usr/bin/bash instead of zsh via /etc/passwd, the issue remains the same.

IMO the issue revolves around this error message I never saw before I had the issue at logon:

Could not get properties: Unknown objet '/org/freedesktop/login1/user/self'

Which looks like a systemd and/or dbus issue.

I am now trying some new suggestions given by an AI before I wipe out my "/"...

Re: [SOLVED] Can't logon: "Could not get properties: Unknown objet"

I'd refrain from both, stupid ShitGPT instructions as well as nuking the system, in doubt you'll end up recreating the problem.

That message, typo or not, isn't in the log you posted.
And google only has https://bbs.archlinux.org/viewtopic.php?id=232933 but that does apparently no lead to a login failure - whatever you see is most likely an outfall of that immediate termination and something grabbing into the gone session.

The login /is/ successful, the session just closes immediately what indicates a problem w/ the shell setup

pacman -Qikk filesystem zsh bash
ls -lR /etc/profile* /etc/zsh*
Sep 16 13:34:56 foo-hostname sudo[995]: pam_unix(sudo:session): session opened for user root(uid=0) by (uid=0)
Sep 16 13:34:56 foo-hostname sudo[995]: pam_unix(sudo:session): session closed for user root
Sep 16 13:35:56 foo-hostname sudo[1346]:     root : PWD=/ ; USER=root ; COMMAND=/usr/bin/timedatectl set-timezone Europe/London

Sep 16 13:35:56 foo-hostname sudo[1353]: pam_unix(sudo:session): session opened for user root(uid=0) by (uid=0)
Sep 16 13:35:56 foo-hostname sudo[1353]: pam_unix(sudo:session): session closed for user root
Sep 16 13:35:57 foo-hostname sudo[1371]:     root : PWD=/ ; USER=root ; COMMAND=/usr/bin/timedatectl set-timezone Europe/London
Sep 16 13:35:57 foo-hostname sudo[1371]: pam_unix(sudo:session): session opened for user root(uid=0) by (uid=0)
Sep 16 13:35:57 foo-hostname sudo[1371]: pam_unix(sudo:session): session closed for user root

How does this happen if you cannot login?

Absolutely, it shows only on screen on the terminal login prompt, flashes 1 sec or so before the screen reset to the logon prompt again:

Your reading of the logs seems more educated than mine, I'll trust you on that.

I'd like to know smile

Just after I did all that, I created a new user just to double check if the issue was really in "/" and not an existing "/home/*"... and I was able to login with it! I am also able to su to my usual user and even start xfce4, even though I had to tinker a lot to get the GUI back.
The good news is I can now have a look at the status of dbus and systemd on my system, the logon issue being still present but workaround-able. I have new leads now, but any educated suggestion based on the above would still be very welcome.

Re: [SOLVED] Can't logon: "Could not get properties: Unknown objet"

returns nothing

It doesn't have to be a literal "exit" call.

and I was able to login with it!

So it's in your $HOME and possibly also in /root

ls -ld ~/.*{profile,rc}

Re: [SOLVED] Can't logon: "Could not get properties: Unknown objet"

Thanks seth, ls -ld ~/.*{profile,rc} gives:

/home/foo/.bash_profile
/home/foo/.bashrc
/home/foo/.nvidia-settings-rc
/home/foo/.yarnrc
/home/foo/.zshrc

Nothing out of the ordinary in these files "unfortunately". I already tried a run while removing everthing from my broken user .zshrc but the result was the same.
I suspect something in / (/etc? /usr?) that has been setup/written in there for my existing users at the time of the issue, like a potential hook during a pacman or yay update that has messed them up but without having anything particular done to their respective ~/

I'm nuking / now, really need that laptop to go back to prod so I won't be able to investigate the root cause further I'm afraid.

Thanks again for your brain-time though, it's much appreciated.

Re: [SOLVED] Can't logon: "Could not get properties: Unknown objet"

Good news, out of sheer luck: while prepping to nuke "/", I started to backup a couple config files in "/etc" I knew I needed.

One of them was a PAM config for USB stick authentication, PAMUSB: I noted this new file "/etc/security/pamusb.cong.pacnew" that was created by pacman as a change of config required by a PAMUSB package upgrade I suppose, and indeed, this config is taking care of the authentication of my current user and root on the machine.

Using the .pacnew instead of my legacy config, I was able to logon again, I guess the legacy config syntax would not be recognised anymore and causing the logon issue.
