  Fails to load nvidia, fails to fallback to intel properly

Status in nvidia-prime package in Ubuntu:

Bug description:
  Fresh install of 15.10, image of 09/06, only synaptic installed 
  Hardware is  i7-4700MQ CPU, Intel® Haswell Mobile Nvidia GT770m

  Initial bootup/ login is fine
  Installed nvidia-352, install went fine, will attach log
  Rebooted to a black greeter screen (heard sound
  Logged in blindly, black screen

  rebooted, at black greeter screen went to tty, purged nvidia*, rebooted.
  Result was a login with no compiz, no unity as the OpenGl plugin was not loaded nor from some further tests could be.
  The only way forward was to remove ~/.config/dconf/user from a tty, then reboot

  Same machine runs nvidia driver via nvidia-prime fine in 14.04.3 &
