xorg - Ubuntu 14.04 login loop - Guest sessions does not work either

I have been using Ubuntu 14.04 soon after it is released. Today I messed something up with the Chinese input ibus, and I don't know if this is the reason at all, but when I reboot using sudo shutdown -r now, I cannot pass the login. I entered the correct password, but then the screen just went black, and then the login screen comes up again!


I have searched quite a few solutions from others, but nothing is working for me.


I have read


I tried to look at .xsession-error, but that file is empty on my computer.


I tried the suggestion of changing the ownership of .Xauthority, but my .Xauthority is not root initially. I also tried to delete it but that does not work either.


I did sudo apt-get remove ibus-pinyin in case it is the problem (but not likely).


I also tried sudo apt-get install --reinstall lightdm, but it does not work either. I also tried dpkg-reconfigure lightdm, but I was not able to see the effect.


Also, I looked at /var/crash, and I saw a file _usr_bin_xpad.1000.crash, which seems to record the crash occured at the time that I first encountered thr login loop problem. Yet I cannot find further clue of how to solve it. At the bottom of that file, it suggested to update several packages if the crash still occurs. I did so but it does not work either. These packages are krb5-locales, libgssapi-krb5-2, libk5crypto3, libkrb5-3, libkrb5support0, libprocps3, procps


Can someone save me...I dont wanna switch back to Windows
