12.04 LTS updated today and now throws me back to login screen after logging in

I allowed the update to run and once it finished, I restarted. Now it will not accept my password. I can log in as a guest, but can not access most of my programs or files. Additionally, when I enter my password, it seems to begin the login process but after the screen flashing black (there are some lines displayed but it flashes too rapidly to see) the system returns me to the log in screen.



I tried logging in in terminal and this is the error I get:

I am a purely cut/paste user. This is really getting to be an issue. For each of the past three updates that required a restart, my system has failed to restart for a variety of reasons...



How can I fix this?
