Ubuntu dont let me login in a graphic session. I type the password (it detects if it's wrong) and even typing it wright the system take me again to login screen.

I've found this other question and run the pastebin command, getting this URL:

http://paste.ubuntu.com/6530253

I've also checked my Home permissions, it's rwx for the owner (me :D)

Thank!

EDIT: when I login in tty1, bash returns an error mensage in the file /etc/profile. Ubuntu had an old copy of this file, so when I use the old copy, it works just fine. Only problem, the upper and left bars (with programs, open things, etc.) didnt show up. I'll try get these back later

I had this problem, and I pulled out the shotgun. I had another sudo enabled account that I logged into. I found that I could 'su' to the affected account, so terminal mode was fine. BUT, I wanted it fixed now, so:

I moved all files out of the home directory of the bad account to /home/store (store was JUST a directory, NOT a home directory for a user).

Make sure to do TWO 'mv' commands. 1} sudo mv /home/bad_account/* /home/store, and 2) sudo mv /home/bad_account/.* /home/store.

Was on Ubuntu, so I then ran sudo deluser bad_account

Then sudo adduser bad_account

Then sudo mv /home/store/* /home/bad_account, and sudo mv /home/store/.*

Then finally sudo chown -R bad_account:bad_account /home/bad_account

bad_account == good_account now.

If the problem is due your Display Manager (DM) this would fix it:

Log-in to a new tty (press ctrl + alt + F1) and enter the commands;

sudo stop lightdm
sudo dpkg-reconfigure lightdm 

then choose gdm as the default DM. After having done that, restart the system to see gdm in effect using command:

sudo reboot


But if want lightdm back, open a terminal and enter:

sudo apt-get install lightdm

Then go to a tty (press ctrl + alt + F1) and enter the following:

sudo stop gdm
sudo dpkg-reconfigure gdm

and choose lightdm to be your default display manager. Restart the system with:

sudo reboot

Guess it's not an problem with Display Manager. lightdm and gdm both dont allow login :( –  Paulo Nesello Dec 7 '13 at 13:50

I don't know, would it create any security problem but using this command can solve your problem

sudo chown 777 .Xauthority

or better use this 'sudo chown youruser:yourgroup ~/.Xauthority' –  Guru Dec 6 '13 at 16:00
    
Not an permission problem. .Xauthority is already owned by my user. :( thx –  Paulo Nesello Dec 7 '13 at 13:37
