Another update: I think I've ruled out nvidia-persistenced being started
via udev as the possible culprit.

I tried Trusty with the nvidia-343 driver from the System76 PPA (which
starts nvidia-persistenced with udev)... and I can connect to WiFi just
fine.

I also tried an up-to-date Vivid install with the same nvidia-343
driver... and again, I can connect to WiFi just fine.

So something specific to Utopic is causing the problem (whether or not
that problem is actually in NetworkManager itself, I still don't know).

Title:
  Cannot connect to WiFi with Nvidia GPU using nvidia-331, SSD

Status in System76:
  Triaged
Status in “network-manager” package in Ubuntu:
  Confirmed

Bug description:
  For some strange reason, we cannot connect to WiFi on hardware with a
  descrete Nvidia GPU (using the nvidia-331 driver) when the system is
  running off a fast SSD.

  Swap the SSD for a platter drive, and things work fine. Likewise, on
  Intel GPU systems, with either an SSD or a platter drive, WiFi works
  fine.

  The failure message is:

  """
  Connection activation failed.
  (1) Creation of object for path '/org/freedesktop/NetworkManager/ActiveConnection/2' failed in libnm-glib
  """

  See the attached screenshot.
