Comment 6 for bug 586503

Many thanks for caring about this problem!
Well, I can't give a unique answer. Here are my (rather strange) results after upgrading to gdm 2.30.2.is.2.30.0-0ubuntu1:
- on one of my configurations (2 desktops upgraded from Jaunty) the /etc/gdm/PostLogin/Default file is now run even if autologin is enabled;
- on the other configuration (the laptop with a fresh install of Lucid) it's still not working as soon as autologin is enabled (but still working ok with manual login).
Let me know if you need more information to further investigate the problem.
