Public bug reported:
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).
