LinuxQuestions.org - help reading xsession-errors-can't log in

I messed up something with xorg but I can't remember what file I edited (i had just copy-pasted from a forum post here about making a samsung monitor work with correct resolution). Now when I try to log in, the screen goes black and it just brings me back to the log in screen. I can enter console only mode.

I'm using Ubuntu 12.04.

I've looked around the net for similar problems but no solution I've tried has fixed it... including reinstalling xorg-xerver, ubuntu-desktop, or resetting configs.

Here's my xsession-errors, if this will help diagnose my problem.
