Arch Linux

Wasn't there a bug report yesterday?

everything works fine here. Are you using systemd instead of initscripts, gnome fallback? more info will be nice

I searched for "dbus" but didn't found anything related to this issue.

Yes, I am using systemd and the normal gnome desktop, so no fallback mode.
What info do you need?

paste the output of pacman -Qii gdm

Here, but this output is while I am using the old dbus:

From my log I think that there is something fishy with the dbus services.

Some parts of the log (If that posted is tldr):

--- Update:
The dbus services comes with systemd... So maybe systemd and dbus 1.6 aren't kompatible?

Before you may ask, here is "pacman -Qii systemd":

I activated the testing repositories and tried dbus 1.6.2, but with no success.
Dbus fails to activate some services:

Jun 28 19:11:19 Primat dbus[510]: [system] Failed to activate service 'fi.w1.wpa_supplicant1': timed out
Jun 28 19:11:19 Primat dbus[510]: [system] Failed to activate service 'org.freedesktop.systemd1': timed out

Jun 28 19:12:12 Primat dbus[605]: [system] Failed to activate service 'org.freedesktop.login1': timed out

what version of dbus-core?

always the matching with the newest pkgrel

1.6.2-2?

I'm sorry Pyro but I cannot parse "newest pkgrel" or "latest version"

dbus-core 1.6.2-2
dbus 1.6.2-1

it should work with -2. Are you sure you have tested properly with that version? as in rebooting your system.

Jep, I rebooted. I got this information from pacman.log:
[2012-06-28 18:35] upgraded dbus-core (1.4.20-2 -> 1.6.2-2)
[2012-06-28 18:35] upgraded dbus (1.4.20-1 -> 1.6.2-1)

What's your login method into your graphical environment?

I'm not sure what you ask, but I try to answer:
systemd starts gdm.service
There I type my password (so not autologin or fingerprint reading)
And then gnome-shell starts
Everything is local, so no ssh login etc.
It's my laptop, so a "standard desktop system"

are the gdm pam modules modified by any chance?
pacman -Qii gdm | grep etc

I already posted the whole output of "pacman -Qii gdm", but here is this part again:

UNMODIFIED /etc/pam.d/gdm-autologin
UNMODIFIED /etc/pam.d/gdm-fingerprint
UNMODIFIED /etc/pam.d/gdm

(Thats my last message for today, but I'm here again tomorrow)

Update from dbus 1.4 to 1.6 also affects slim in the same way ... x server starts but screen is black and the mousepointer is a watch.

/var/log/slim.log contains:
slim: open_session: Unable to open session: Message did not receive a reply (timeout by message bus)

I tried slim now.
First with dbus 1.4.20-1 and dbus-core 1.4.20-2:
It works flawless. Greeter appears, login and gnome-session with gnome-shell starts.

Then I tried it with dbus 1.6.2-1 and dbus-core 1.6.2-2:
Greeter appears, I can type my username and password but after pressing enter and some loading time I get to the tty1.

Here some error messages in the slim.log file:
slim: open_session: Unable to open session: Activation of org.freedesktop.ConsoleKit timed out
slim: open_session: Unable to open session: Connection was disconnected before a reply was received

I used a minimal slim configuration, so I only configured it, that it starts gnome-session.
Maybe Jiri configured slim with gnome-keyring support.

can yo do ls /run/console when using dbus 1.6.2?

There is no output.

probably related https://bugs.archlinux.org/task/30476

Neighter `systemd-machine-id-setup` nor `dbus-uuidgen > /etc/machine-id` fixed the problem.

Same issue here. I did fresh installation of archlinux and after upgrade gdm as well as nm-applet can't find dbus session.
Rolled back to dbus 1.4 as Ticket owner suggested - it worked. Can provide logs/cmd outputs if you need.
Tried kdm/slim - it works fine with dbus 1.6

Problem is fixed for me. I'm running dbus 1.6 now without any problems with NM or GDM.
For me it was because of filesystem package upgrade issues and /etc/group.pacnew file was not resolved for me.
I've noticed that dbus group is not anymore exist in group so I resolved /etc/group file and rebooted

PS. Some issues with 'filesystem' package upgrade: I removed /var/run directory to be able to install it.

After those steps I was able to work with dbus 1.6 version. Please check if you can solve it this way.

I already updated the filesystem package with the force option and it did work that time.
With your remark I did the following: `rm -rf /var/run /var/lock && pacman -S filesystem` to reinstall the filesystem package.
Then updated to dbus 1.6, rebooted and it works.

Thanks for all your help!
