Hi, normally I don't have a PW as user (my machine is private), I have set now one to test. For me it seems, that there is a timer (about 10 -15 sec?) running. When I tested this, immediately after logoff user, I can not login. Trying 2 to 3 times, about the 3rd time I can login again. If I wait about 20sec after logoff user, I can login immediately.

It happens very often that after logging out and trying to re-login and after having entered the correct password at the gdm prompt, the login is rejected, so as if trying a wrong password. Something it helps to kill gdm, but not always. Perhaps some hint in /var/log/messages: Sep 25 08:54:17 eule /usr/libexec/gdm-x-session: Fatal server error: Sep 25 08:54:17 eule /usr/libexec/gdm-x-session: (EE) xf86OpenConsole: Cannot open virtual console 3 (Permission denied) Sep 25 08:54:17 eule /usr/libexec/gdm-x-session: (EE) Sep 25 08:54:17 eule /usr/libexec/gdm-x-session: (EE) Sep 25 08:54:17 eule /usr/libexec/gdm-x-session: Please consult the Fedora Project support Sep 25 08:54:17 eule /usr/libexec/gdm-x-session: at http://wiki.x.org Sep 25 08:54:17 eule /usr/libexec/gdm-x-session: for help.

[AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series] I filed already a BZ (https://bugzilla.redhat.com/show_bug.cgi?id=1260487), but getting no answer. The gnome mega update has been applied yesterday, but there is no difference in behaviour between before and after! If using lightdm instead of GDM, no such problems! Anybody sees this too or knows some workaraound?
