Lucid->Maverick login screen GDM failure

[klotz]

I upgraded from Lucid to Maverick. The GDM login screen presents no usernames. I couldn't log in.

Below are symptoms and the workaround I did, which is probably incorrect. However, after the workarounds, I could log in.

I see some bugs in Fedora about permissions with this file but they claim it's OK in Ubuntu: https://bugzilla.redhat.com/show_bug.cgi?id=607715

I checked permissions:

ls -l /lib/dbus-1.0/dbus-daemon-launch-helper
-rwsr--r-- 1 root messagebus ... /lib/dbus-1.0/dbus-daemon-launch-helper


Workaround:

I did chmod a+x /lib/dbus-1.0/dbus-daemon-launch-helper

Workaround:
I did

mkdir /var/run/console
