I'm facing a similar problem, and have found some other users that went with this problem too, so I agree with those defending that importance level should be raised.

I'm running Xubuntu 9.10 (x86_64) on a Dell D520 latitude. It's a fresh install made yesterday and after installing I did logon, suspend and resume normally, no problems at all. However after first logout subsequent logins fails with "authentication failure". This process happens with *every* account (I created 2 more account and they all show the same behavior). The only way to logon into the system again is bypass gdm and logon in consoloe by either pressing <ctrl>+<alt>+<f1> or to reboot in rescue mode and select "resume normal boot".

Reinstalling GDM did not fix this.

I've faced the same proble twice before that, once I was running Ubuntu, and the second time I was running Ubuntu with XFCE4. Both times it was 9.10 version.

The only unusual thing in my notebook is that battery is dead, never charges beyond 4~8%. Not sure if this could be related, however gdm logs does mention some errors related to "power managment".

:0-greeter.log says:

The failures are reported in auth.log like:

Nov 13 14:17:37 hobbes gdm-session-worker[1469]: pam_unix(gdm:auth): authentication failure; logname= uid=0 euid=0 tty=:0 ruser= rhost=  user=eric

Apart from those messages, could not find anything else that seems related.
