This happened on my Dell M3800 with the Optimus Nvidia GPU and nvidia-prime when updating to the 14.04.5 LTS HWE.

The workaround I used was to force the modesetting driver in xorg.config for the Intel GPU, and not allow changes to xorg.config (see https://vxlabs.com/2015/02/05/solving-the-ubuntu-14-04-nvidia-346-nvidia-prime-black-screen-issue/).

An updated ubuntu-drivers-common to make gpu-manager use the modesetting driver will be most helpful.
