Immediately after login, the screen freezes--except for the cursor

[Bryan Agee]

In kernel 3.16, I could still launch a terminal and see that it was open by the changing of the cursor; the window did not draw (nor did anything else aside from the cursor).

On switching back to 3.13, untiy does not load at all, and the Ctrl+Alt+t short cut does not work.
