Had exactly the same problems as described here since this morning when kernel was updated to 3.19.0.31 via update-manager. My system is ubuntu 14.04 LTS. With the vivid kernel. Booting with the old kernel, 3.19.0.30, makes everything working again. But trying with 3.19.0.31 seems to totally hang everything after having logged in, unity doesnt display or actually i got it displayed one time but then i had no mouse and no control and ctrl alt f1 didnt work. So I guess there is something terribly wrong with the -31 kernel.
