Recent update has me stuck in a log in loop

Question

So I tried rebooting my pc recently and now it won't let me log in. It just kicks me back to log in screen

I've tried rm./home/*/.xauthorith Cannot remove is a directory

And a few of the other more common ones like purging nvidia. Just said the was no nvidia to purge

Answer 1

In terminal, type (use the correct username):

cd /home/your_username
ls -l .ICEauthority # (that's a lower case L)
ls -l .Xauthority   # (that's a lower case L)

If either ls command returns one of these (where it shows root, instead of your username):

-rw------- 1 root root 242476 Nov  6 12:48 .ICEauthority
-rw------- 1 root root 58     Nov  6 12:48 .Xauthority

Then type (changing your_username to the correct username):

sudo chown your_username:your_username .ICEauthority

and/or

sudo chown your_username:your_username .Xauthority

Answer 2

Changing ownership didn't help me, but rolling back nvidia-304 helped. I've described it here: stuck in login ubuntu 14.04 after trying everything
