Just finished upgrading from Ubuntu 13.04 to 13.10. Everything works fine. After the installations, I restart to finish the installations. In the log in screen, I put my password and then it goes back to the log in screen. I've tried so many times, still the same.

Note: Using Unity, running 13.04 before using MacBook Air with single OS.

I had the exact same issue after upgrading from 13.04 to 13.10.
None of the solutions here worked for me, so I found this bugreport. I removed Cinnamon/Nemo with sudo apt-get remove --purge cinnamon* and sudo apt-get autoremove and now everything works fine.

I had the same issue. Tried cinnamon didn't work. Read about the permission issue on the .Xauthority file. Sorry, I lost the link to that answer

  1. Logged in with Ctrl+Alt+F1 as the user

  2. and removed the .Xauthority file

  3. went back to GUI session by Ctrl+Alt+F7

Worked like a charm!!

At the login screen press CTRL+ALT+F1 and login as normal user, then execute:sudo su
No errors should happen (if errors happens write them here!) and your prompt will be with an "#" character at the end, you are root now: don't do stupid things and run exit to return a normal user.
After this check let's reconfigure your login manager, execute: sudo dpkg-reconfigure gdm and, eventually, select gdm as your default login manager.
Execute sudo killall Xorg; after that you will be asked to login (if don't press CTRL+ALT+F7) without any error: try to login.
If it still don't work, press CTRL+ALT+F7, run passwd and change the password; execute sudo killall Xorg and try to login with the new password.
If it still doesn't work (damn! :-) ) return to the virtual terminal and execute rm ~/.Xauthority, then sudo killall Xorg and try to login.
The password asked with "sudo" is your user password, never forget your password.
If the login still doesn't work, it's a more complicate case, report here any error.

I could temporary get past this problem by changing from Ubuntu Default to Cinnamon, at least it lets me access the files. Really wondering why is it Unity's broken...

I had that same issue, i was not having cinnamon installed. Just the default Ubuntu desktop environment. After looking for alternatives without success, i did the following that fix my problem.

  1. Since it is impossible to login back with Unity, i took the decision to install cinnamon on it (which will break Unity)

  2. At the login screen press CTRL+ALT+F1 and login as normal user.

  3. Type in the following commands: 

    sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable
sudo apt-get update
sudo apt-get install cinnamon

  4. After installing all the necessary packages, just log out and change the log-in option to Cinnamon.

  5. You should be able to log into your system now with Cinnamon.

I believe the problem is with Unity, can't find out how or why but a great fix to that issue will be awesome.

I had this problem this morning just after running some regular updates - I tried all sorts of things like deleting .Xauthority etc but in the end I tried reinstalling my nvidia driver which seemed to fix the login screen problem.
