Tested with proposed repository, system could boot to desktop successfully.
Test steps: 1. Enable trusty-proposed in software-properties-gtk 2. sudo apt update ; sudo apt upgrade -y 3. Reboot system 4.

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). [Test Case] 1) Enable the trusty-proposed repository, and install the ubuntu-drivers-common and the nvidia-prime packages. 2) Install the nvidia driver. 3) Restart the system and see if it boots correctly. If unsure, please attach your /var/log/gpu-manager.log and /var/log/Xorg.0.log [Regression Potential] Low, the above mentioned changes are already in Yakkety (and most of them have been in Xenial since its release).
