Sebastien, After manually starting gdm using 'sudo gdm' I get the same issue. Gdm starts, i see the new gdm login theme load up with the box asking for my username, the username box then quickly disappears and I get the message "Authentication Failed". After that no keyboard or mouse buttons have any effect. All I can do from that point is push the power button to trigger a reboot. I'm not really sure which logs i should be checking or where to find them. I did check /var/gdm/0.log but i don't think there is anything relevant in there. I'll attach it anyway.
