When the gdm-fallback session used, and the user types a wrong password, it is not possible to log in with the correct password after that for any users. GDM shows that the user logged in, but the user session does not start in fact. It does not happen with the gdm-shell session.

Additional info:
* package version(s)
systemd 196-2
pam 1.1.6-1
gdm 3.6.2-1.1

Steps to reproduce:
1. Enable gdm.service in systemd and ensure that gnome-shell is not installed.
2. Reboot your computer, gdm-fallback session starts.
3. Try to login with a wrong password. It causes that the authentication failed.
4. Try to login with the correct password. Now GDM shows that you logged in, but nothing happens, the user session does not start.
This task depends upon

Now I reported the bug for upstream:

Ther are some fixes in the gnome-3-6 branch for gdm. But they are not yet included into the arch package.

Please test with gdm 3.6.2-2.

I tested with gdm 3.6.2-2 now, but it still happens.

Did you actually restart gdm after installing the update?
Comment by György Balló (City-busz) - Monday, 18 February 2013, 19:17 GMT
Yes, I tested after a reboot.

I just want to confirm that this problem is still here in a completely new installation of arch.

package version(s):
gdm 3.6.2-2
systemd 198-1
pam 1.1.6-1

Have the same trouble. but I use xfce4 if it matters at all.

gdm-fallback session was disabled in GDM 3.8, so it's no longer reproducible.
