I face a login loop and I am unable to login.

I tried reinstalling lightdm, ubuntu-desktop, but doesnt help. I installed gdm and used it as my default for a while to see if it was a lightdm issue.

But here it seems like that there are 3 incorrect password attempts on something that starts when I login. I think my sudoers file is correct.

Here is my auth.log -

May 23 14:52:01 ubuntu-desktop lightdm: pam_unix(lightdm:session): session closed for user lightdm

What if you boot to a different runlevel? Also, try disabling services in init.d. See Starting services at boot in Linux –  Tom May 24 '12 at 2:33
    
Give more information on what you mean with "a login loop". Do you enter tha password, press Enter, and then just get prompted to enter it again, or what do you mean? –  Daniel Andersson May 24 '12 at 9:12
