Login goes back to login screen

Question

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

Solution

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

sudo chown 777 .Xauthority

"when I login in tty1, bash returns an error mensage in the file /etc/profile" What is the complete and exact text of that error message, and do you have any reason to think this error is related to your inability to log in graphically? (I suppose it could be--with most desktop environments, ~/.profile does get sourced on graphical login.) When you use the backup of .profile that doesn't produce the error, does that appear to affect the behavior of the graphical login screen in any way, when you try to log in?

or better use this 'sudo chown youruser:yourgroup ~/.Xauthority'

Guess it's not an problem with Display Manager. lightdm and gdm both dont allow login :(
