This might sound noobish, but, I wanted to change my username and password of my computer(ubuntu 12.4 I think) I changed the password, and it worked, I changed the username - and it worked, so I logged out and tried to log back in, but every time I enter the new password, the computer goes to a black screen for a sec, then goes back to the log-in page,

the only way I can login is by going in with guest. and I can't delete anything because I don't have permission

after doing 

mount -o remount,rw /
cd /home
ls -al

this is the output:

total 16
drwxr-xr-x 4 root root 4096 mar 18 09:03 .
drwxr-xr-x 23 root root 4096 mar 18 09:49 ..
drwxr-xr-x 3 root root 4096 mar 18 09:03 .ecryptfs
dr-x------ 3 itay itay 4096 mar 18 09:09 itay

so i did this: mount -o remount,rw / cd /home chmod u+w itay

mount -o remount,rw / cd /home/itay mv .Xauthority .Xauthority.backup

now it logged in to my user, but i can login in terminal, what can i do?

This problem sounds very similar to me.

Go to recovery-root-shell, type in: 

mount -o remount,rw /
cd /home
ls -al

Pls post your output here, maybe you have the same problem :)

Edit 1: This sounds good, you can try following commands in the recovery shell:

mount -o remount,rw /
cd /home
chmod u+w itay

When this command don't solve your problem you can try STRG + ALT + F1 at the graphical login and try to log in in the commandline. When the login in the commandline works you can try the following commands (recovery):

mount -o remount,rw /
cd /home/itay
mv .Xauthority .Xauthority.backup

And now try again to log in :)

If this don't help, I think saiarcot895 give you already the right answer.
