I have a problem accessing to my Ubuntu 13.04 system. Recently I updated from 12 to 13 and after some hard work I am able to input my password and user name, but I can't get any further, because the system doesn't recognize my password and/or account. So I have no access to the graphic environment, only to a terminal. Some people told me that may be it's a resolution problem. Can somebody tell me what's wrong and what should I do?

you could try to enter:
sudo apt-get update
sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install lightdm
and then in the terminal enter:
sudo apt-get install gdm
and then you chose lightdm.
Try to make a new account and chek if you can login:
sudo useradd -m username
sudo passwd username
Try also what Michael said:
sudo apt-get update
sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install lightdm
Followed by the last command:
sudo apt-get install gdm

I did what Michael said, but it doesn't work. And so I try your recommendation and now I can get in on my graphical environment, but now the problem is that I don't have acces to my super user account because the system still doesn't whant my password. What should I do? Thanks a lot for your answers. May 31, 2014 at 4:56

Sorry, my mistake. I have acces to sudo user, it was a lenguage configuration keyboard problem. Thank you. One more question, do you recommend to update my system to the 14.04 version? May 31, 2014 at 5:07

I had similar problem with 16.04. The cause was my graphic adapter driver (newer versions of Xorg, Lightdm or whatever after update/upgrade conflicted with it). Reinstalling/updating Nautilus, Xorg etc. didn't help but complete uninstall of graphic driver did the job. In my case it was Nvidia so I typed to the command line sudo apt-get purge Nvidia*
, then restarted. Of course it started with crapy resolution and required to reinstall the driver but it worked and works so far.
So the sequence that worked for me was:
sudo apt-get update
sudo apt-get install lightdm
sudo apt-get install gdm
(then choosed lightdm)
sudo apt-get purge Nvidia*
sudo reboot
The "password loop" disappeared and then I just installed again my Nvidia driver to restore acceptable screen resolution.
