Description of problem:
I had to explicitly do a:
gconftool-2 --set --type boolean /apps/gdm/simple-greeter/disable_user_list false
as the gdm user in order to bring back the list. Is this intentional? (if it is, then that is an idea that should be reverted). This is with gdm-2.29.5-2.fc13.
Still same problem..
From what I read on the test mailing list, it is intended that the user list be displayed. Did you manually change disable_user_list at some point in the past? Was this a fresh install or an upgrade? Are you experiencing sound glitches or similar error messages to those described in bug 555593?
You're hitting a race condition in ConsoleKit activation. The default value of that setting hasn't changed.
The update in bug 555593 should fix your problem. If it doesn't, let me know and we investigate more.
