Red Hat Bugzilla – Bug 450330
Last modified: 2015-01-14 18:21:22 EST
Description of problem:
gdm crashes. Not sure what info helps debugging this; this is on my laptop
(Lenovo T60) using the internal display. X.org starts fine if I boot into
runlevel 3 and run it with startx; there are also no errors in Xorg.0.log when
the gdm crashes happen and gdm gets to the point where it displays the login box
with the box saying just 'Other...'
The only unusual things I can think of are that I have gdm set to log me in
automatically, and that my homedir is automounted, though from the laptop
locally, so that it is bindmounted.
Version-Release number of selected component (if applicable):
The /var/log/messages is at http://lutter.fedorapeople.org/messages-gdm-crash.log.gz
This gets weirder: while I was trying to figure out what exactly causes the
crash, I changed my home directory by editing /etc/passwd from /homes/lutter
(the bindmounted one) to /home/lutter (ext3 file system, target of the bindmount)
Sure enough, that makes gdm behave again, and the greeter comes up and I can log in.
The strange thing is that when I changed my homedir back to /homes/lutter, gdm
kept behaving, even after a reboot. I can now log in, even with my bindmounted
homedir. Does gdm cache any information in separate files ?
not that would affect this.
It stores a file in the users home directory called ~/.dmrc, and it stores some
transient information per login in /var
ConsoleKit stores some information about the users in /var/log/ConsoleKit.
Note the gdm that shipped in F9 GA fell over in the scenario where the home
directory wasn't available early enough because of a last minute change before GA.
We pushed an update afterward that should address this issue (see bug 445613).
The update was in the version you mentioned (gdm-2.22.0-5.fc9).
Could it be you installed the update but hadn't restarted gdm yet and that's why
the reboot "fixed" things?
looking at the log I see:
Jun 6 09:29:03 galia console-kit-daemon: WARNING: Couldn't connect to
system bus: Failed to connect to socket /var/run/dbus/system_bus_socket:
This suggests the system message bus wasn't running which could cause all sorts

No, because I went through several cycles of 'boot - gdm keeps crashing -
reboot'; the crashing kept happening consistently on reboot until I changed my
home dir from autofs -> local partition and then didn't reappear after a change
from local partition -> autofs.

This is from the shutdown preceding the first time I encountered the problem;
subsequent reboot attempts start at Jun 6 09:47:54
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
