Running 13.10 x64 on an Ubuntu laptop (System 76 Kudu Professional).

When I bootup and provide my password; the screen goes black for a moment then returns to the login screen.

Switching tty I am able to login; then start X (using startx or startx unity).

How do I resolve this issue?

My /etc/environment was corrupted; fixing that solved this issue.

Can you explain how you did that? – Seth Apr 3 '14 at 23:18
I rsync'd the /etc/environment from one of my servers; replacing my own with that one. – A T Apr 4 '14 at 7:06
