I meant that you would copy the output from those commands, and post it here.
Since you apparently are logged in as root, you need a slightly different command for .xsession-errors. If your username is abby, it would be:
cat /home/abby/.xsession-errors
and probably also
cat /home/abby/.xsession-errors.old
Please note that you need to do this instantly after a failed attempt to log in as your user.
