Ok, your config doesn't show anything weird "WARNING: Failed to open log file /var/log/lightdm/x-0-greeter.log: Permission denied" is an issue happening for everybody it seems and likely has to do with some of the privilege drops fixes from before Oneiric, it's worth a new bug if nobody opened one yet but it's not what is breaking your system
your lightdm.log has "[+2.52s] DEBUG: Launching process 13148: /usr/lib/lightdm/lightdm-greeter-session 'unity-greeter' [+2.52s] WARNING: Failed to open log file /var/log/lightdm/x-0-greeter.log: Permission denied [+2.52s] DEBUG: pam_setcred(0x230e7e0, PAM_ESTABLISH_CRED) -> 0 (Success) [+2.52s] DEBUG: PAM returns environment 'TH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games LANGUAGE=de_DE:en LC_MESSAGES=de_DE.UTF-8 LANG=de_DE.UTF-8' [+2.54s] DEBUG: Process 13148 exited with return value 0" Which is weird, notices that it starts at "TH=..." on my log I get "DEBUG: PAM returns environment 'PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games LANG=fr_FR.UTF-8'" so it seems somewhat you pam environment get mangled, that might be a different issues from the ones on this bug, could you restart your box in its current state and open a new bug using "ubuntu-bug lightdm", it should attach your log infos etc what do you have in /etc/environment?

Before the login screen Ubuntu prints out some state messages. The last one is "Checking battery state" (mine it is not a portable PC) I have to press Alt+F1, I logged in and wrote "startx". Gnome3 says "Failed to load session "gnome-fallback"" (my pc doesn't support neither Gnome-shell nor Unity3D) and pressing the only button Log Out terminal compares again. Is it possible to rollback last upgrade of Lightdm?
