Login issue with GDM

Hi,

I can't login into Gnome anymore. Usually GDM offers a list with users and now there is no list. I've had a look in the Bugtracker and I've also searched the forum and no luck. I have seen that there was a GDM update and probably that is the issue. I've checked the gdm log files in /var/log/gdm but that was not very helpful. Last time I've had a similiar problem there was an issue with /etc/pam.d/gdm but the file looks just fine. So probably somebody has an idea or can point me into the right direction (where I should look)?

Thanks in advance!
Michael

Re: Login issue with GDM

You can have a look at the gdm's greeter logs. (/var/log/gdm/...)

If you find: "Failed to execute program /usr/lib/dbus-1.0/dbus-daemon-launch-helper" or similar,
doing a "chmod o+x /usr/lib/dbus-1.0/dbus-daemon-launch-helper" might help you.

I experienced this some months back: http://bbs.archlinux.org/viewtopic.php?id=92872

But there could be something completly different, only the log's can tell...

Re: Login issue with GDM

Hi,

thanks for the quick reply. I've had a look at the log but I'm not quite sure if that is really the problem. If I restart the daemon everything works fine. Here is a snippet from /var/log/gdm/:1-greeter.log

Probably the problem is "org.freedesktop.PolicyKit1.Authority"? I will google if that is a problem.

Re: Login issue with GDM

I have the same problem, but it lets me input my username and password when I switch to tty1 and kill gdm-simple-greeter O_o

Re: Login issue with GDM

Hi,

sorry for the late reply. I've reinstalled the gdm daemon and it worked out for two of ten times. At present the best solution is to restart the gdm daemon which offers user options after the restart. Any other suggestions?

Thanks in advance!
Regards,
  Michael

Re: Login issue with GDM

*Update*: The gdm issues are on my notebook and I've got the impression that there was a connection between the ability to login through gdm and connecting my notebook to the power supply. Unfortunately I was wrong. Any other ideas?

Re: Login issue with GDM

I'm having the same issue, no user selection. Reinstalling gdm didn't help either. After booting I have to alt-f1 and restart gdm to be able to login.

Re: Login issue with GDM

I've filed a bug report. Are you using i686 or x86_64?

Re: Login issue with GDM

I'm starting gdm through rc.conf, but I've found in /etc/inittab the following line uncommented

#x:5:respawn:/usr/bin/xdm -nodaemon

I've added a hash and it seems to solve the problem. I will check it on my desktop if it's the same problem. Maybe you'll have a look in your /etc/inittab?

doesn't really matter if your default runlevel is still 3. to start gdm using this method, comment out that xdm line and uncomment the gdm line and modify the default to 5

#id:3:initdefault:
id:5:initdefault:

Re: Login issue with GDM

Yepp, you're right. Nothing has changed. I'm still confused why gdm is not working anymore after the last update (everything worked fine).

Re: Login issue with GDM

The same problem here. And the same (temporary) solution as suggested by JAORMX.
1) go to tty1 (CTRL+ALT+F1)
2) find out gdm-simple-greeter process number (ps -A | grep gdm)
3) kill gdm-simple-greeter (kill <process number>
4) switch back to tty7 (CTRL+ALT_F7)
And the user list is there as it should.

You can find a similar solution in the Bugs forum, but this one seems to be nicer because you do not need to restart gdm from the console.

I have this problem on an old desktop:  Pentium2, 400MHz,  RAM 396 MB.
I do not have this problem on an 800MHz desktop, nor a 2.2 GHz 4GB laptop.

Hope, developers will find a real solution to the problem of what it seems freezing gdm-simple-greeting.

Re: Login issue with GDM

Bad news. The disease is spreading out.
I have updated the system today, and got the same bug on my newest laptop (HP dv5, 4GB). In the meantime I still have the same problem on my old computer,

Re: Login issue with GDM

Here you can find a bug report (http://bugs.archlinux.org/task/20152), but there's still no solution. Maybe someone can find out more if I post any logs, but I don't know exactly which could be relevant.

Re: Login issue with GDM

On a fresh-installed Arch System it doesnt happen. Even if you try it 12398721983 times so maybe its an upgrade issue

Re: Login issue with GDM

Same problem here. Sometimes gdm works, sometimes it shows no user, and the only way I've found to proceed is by killing the gdm-simple-greeter process.
Tail of :0-greeter.log when gdm fails to work:

Apparently the problem deals with the running of ck-history and the process of enumerating users. Since I'm the only user of this computer, I'm bypassing the problem by using the Autologin feature. Let's hope the bug will be corrected soon, anyway!

Re: Login issue with GDM

Just do a

rm /var/log/ConsoleKit/history*

The new patches to consolekit and gdm should then prevent the problem from occurring again.
