Bug 268567 – gnome-base/gdm-2.20.10-r1: unexpected logout due pam problems

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Pacho Ramos 2009-05-04 09:41:45 UTC]

Seems that I am suffering these strange problems since updating from 2.20.10 to 2.20.10-r1 (I have just downgraded again after other logout for testing).

From time to time, X gets restarted due errors like these in /var/log/messages:

There should be no difference in installed files by gdm-2.20.10 and -r1 given the flags you mention. The pam errors you list though might suggest that something gets borked at pam level. Did you customize your pam stack ?

Not at all, because I don't know anything about pam. Maybe it's because of pambase update due new gdm requeriments (from stable to current testing version) :-/

[Comment 4 Gilles Dartiguelongue (RETIRED) 2009-05-04 19:40:45 UTC]

could be, tried downgrading only gdm I guess ?

I downgraded only gdm, but I am still trying (I couldn't use computer during all the day as you probably can understand :-))

please get back to us.

Seems that I don't suffer this problem anymore with:

I can't reproduce this problem even why I updated my 2.24 box to gdm-2.20.10-r1 and latest pambase.

I will update again to -r1 for see if it reappears then

I haven't seen this from a while
