GDM Update

I'm getting the following error after update GDM

-- Logs begin at Sat 2018-09-08 12:24:43 JST, end at Sun 2018-09-30 13:12:19 JST. --
sep 30 13:12:04 arch gdm[588]: GLib-GObject: g_object_add_weak_pointer: assertion 'G_IS_OBJECT (object)' failed

sep 30 13:12:04 arch gdm[588]: GLib-GObject: g_object_add_weak_pointer: assertion 'G_IS_OBJECT (object)' failed

And looking at systemd

$ systemctl status gdm
● gdm.service - GNOME Display Manager
   Loaded: loaded (/usr/lib/systemd/system/gdm.service; enabled; vendor preset: disabled)

sep 30 13:12:04 arch gdm[588]: GLib-GObject: g_object_add_weak_pointer: assertion 'G_IS_OBJECT (object)' failed

What is this problem?

GLib-GObject: g_object_add_weak_pointer: assertion 'G_IS_OBJECT (object)' failed

I also would like to fix the "gkr-pam: no password is available for user" thing, but hadn't too much luck.

Thank you in advance!

Re: GDM Update

I've done what mmarzantowicz said:

Before proceeding, please make appropriate backup.

Remove new directory created by accountsservices

# rm -rf /var/lib/accountsservice

Then create symbolic link to old directory

# ln -sf /var/lib/AccountsService  /var/lib/accountsservice

Now either reboot or restart gdm.service and accounts-daemon.service.

Please, let me know if it helped.

but still getting this error:

arch gdm[578]: GLib-GObject: g_object_add_weak_pointer: assertion 'G_IS_OBJECT (object)' failed

Re: GDM Update

What about the other error messages?
Can you login w/o autologin?

Re: GDM Update

Here's what I've got today

oct 01 09:54:21 arch gdm[673]: GLib-GObject: g_object_add_weak_pointer: assertion 'G_IS_OBJECT (object)' failed

and no password error from the start, but if I close the session and login again, the error appear

oct 01 10:42:20 arch gdm-password][3342]: gkr-pam: the password for the login keyring was invalid.

Can you login w/o autologin?

Yes I can. Then the password error appears. It also appears from the start if I setup a cron job, and the cron job doesn't execute. But I don't know if this is related or not...

Re: GDM Update

Try to downgrade accountsservice rather than the path renaming/symlinking.
The assertion is  most likely a follwo-up error for some unpredicted nullptr and the behavioral pattern and timing fit the accountsservice issue.

Re: GDM Update

On my newly installed system, accountsservice is still causing problems. Downgrading to 0.6.50 solves the problem, but this should be looked at in more detail.
