I can't login neither as root or user. It won't let me login at all

[Teenna]

Hello sorry for my grammar this is not my mother language
My problem:
I started my PC today "normally" and suddenly a gray square appeared in the middle of my screen telling me that my session last 10 seg and that I have lo login as "fialsession". I tried that but I only can got in with the terminal.
It said: "Can not open or create *(null)*,this indicate it can be a problem with your configuration, error:"Failed to create file '/tmp/gconf-test-locking-file-RZWBKU' Permission denied"(errno=2)
I'm here sitting and waiting (and getting in panic).
Yesterday I installed Picasa 3 and stopped cherokee from starting with the system, else I realized that I couldn't find my .bashrc file
Im really a baby here, just borned into Debian a week ago.
I really appreciate if anyone can help me.
Thanks for reading.

This might be a permission problem on you're /tmp directory. Try changing it by typing as root:

# chmod -R 777 /tmp

Then try logging in again.

THANK YOU VERY MUCH

I'm glad you joined today. I open tty login as root, typed what you wrote and
you did it.
