Effects 64-bit also

[Daniel Santibáñez Polanco (dansanti)]

when i click on unlock..

[Rubén Parra (rubenxparra)]

I reply the bug when click in System>Adminitration>Login Screen

[Kåre Birger Lapstuen (lapstue)]

Happend for me on 64-bit version of ubuntu 9.10. Crashes when I click unlock.

[Tom Pino (metalsmith-rangeweb)]

I am on 64bit and it crashes just about when you have time to read the window to find unlock but to fast to actually click anything.

[Tom Pino (metalsmith-rangeweb)]

I thought I would try to bypass the sign-in for the gdm by "sudo gdm" in terminal;

ken@ken-desktop:~$ sudo gdm
[sudo] password for ken:

** (gdm-binary:3835): WARNING **: Failed to acquire org.gnome.DisplayManager

** (gdm-binary:3835): WARNING **: Could not acquire name; bailing out
ken@ken-desktop:~$

[FrozenFish (frozenfish91)]

Crashes few seconds or almost immediately after launch when launched normally but when I start it in sudo it stays up and don't crashes.
When I then click the unlock button blanks out and nothing happens (not even in the terminal).

[Hellsgator (hellsgate)]

same issue here. crashed when opening it in control center.

[fastfret79 (markfoxwell)]

Same as...

mark@karmic:~$ sudo gdm
[sudo] password for mark:

[Sebastien Bacher (seb128)]

Confirming due to the number of duplicates, the dialog is working correctly there, could be similar to bug #410727

[Sebastien Bacher (seb128)]

Did you restart gdm after the upgrade? Is somebody having the issue on an intel installation?

[Sebastien Bacher (seb128)]

Could somebody get a debug stacktrace?

[Sebastien Bacher (seb128)]

The tool is not meant to be run using sudo since it use policykit, running it with sudo is an user error and not a bug

[Crsim (crsim)]

I did not try to run it using sudo.

[Hippu (teemu-heinamaki)]

Rebooting does not solve the bug. I attached the stacktrace from apport with the -dbg package installed.

Sebastien,

is there a solution in this bug report?

[C de-Avillez (hggdh2)]

@Wayne: The bug was still marked as private due to the stacktraces. I looked at them, and did not see anything warranting a Private status, so I reset it. You can now access it.

Sorry for that, but sometimes stacktraces do contain private data, and we try to be careful on them.

[Alessandro Ranaldi (ciaolo)]

In vb (with intel pentium host) it closes, in real installation (intel atom, a netbook) it works well.

[Taralyn Darkchylde (hellion0)]

Had the same thing just happen, message is pretty much the same as initial report.

From dmesg:

[Sebastien Bacher (seb128)]

could people having the issue add their /etc/gdm/gconf.gdm and custom.conf there?

[Fabian (fabian-h)]

I'm experiencing this bug on a VM running the latest Karmic. I did not change any settings regarding gdm, they should all be default values. I don't even have any gdm.conf or custum.conf in /etc/gdm (There is ony a gdm.schemas).

[Michał Mrówczyński (ups5)]

For a true installation (clean install on Acer Aspire Ine 150 BB), is not working properly. This requires the use of from time to time command restart netbook-launcher

[Michał Mrówczyński (ups5)]

It's "netbook-launcher restart" command, of cors.

[Hippu (teemu-heinamaki)]

The gconf.gdm file doesn't exist, but the rather empty looking custom.conf is there.

[Taralyn Darkchylde (hellion0)]

@ #28: Neither file mentioned exists on my system.

[Wayne Cat (exchange)]

Sebastien,

the files also do not exist on my system

------------
root@macbook:~# ls /etc/gdm
gdm.schemas Init PostLogin PostSession PreSession Xsession

[Sebastien Bacher (seb128)]

the issue happen when there is no key in custom.conf yet, I've a fix locally now

[manzur (sl-solaris)]

we have too see that fix first, because a bad treatment brings more problems

[bert07 (marien.bert)]

The latest update with "gdm" in it, did not resolve anything here.

[Andrew O'Brien (ar-obrien)]

Hmm, I don't have any keys set in custom.conf, and I don't have a gdm.conf (at least not in /etc/gdm). I do have a gdm.conf.dpkg.bak, which I have attached, dated 2009-04-03.
Did a recent update of gdm remove this file by mistake?

[Sebastien Bacher (seb128)]

the update has not been uploaded due to the alpha freeze being in effect

[Launchpad Janitor (janitor)]

This bug was fixed in the package gdm - 2.27.4-0ubuntu11

---------------
gdm (2.27.4-0ubuntu11) karmic; urgency=low

  * debian/patches/09_gdmsetup.patch:
    - clean some unused variables there
    - don't crash if there is no autologin key in the configuration yet
      (lp: #410475)
    - don't specify encoding in desktop entry (lp: #410591)
  * debian/patches/11_crash_for_apport.patch:
    - don't catch crashes so apport can do its job
