Bug description:
  A recent security update of the nvidia driver provided new EGL
  libraries, which are not handled by the current gpu-manager (ubuntu-
  drivers-common) and nvidia-prime in 14.04. This problem is fixed in
  Xenial or newer.

  ubuntu-drivers-common also does not distinguish between the different
  LTS stacks, and this is a major problem on Intel+Nvidia hybrid
  systems, as anything running stacks older than 14.04.5 will require
  using the intel driver with SNA acceleration, whereas the rest should
  use the modesetting driver. Boot parameters can also be passed to use
  other driver combinations (for unsupported use cases).
