[Bug 1388130] Re: Cannot connect to WiFi with Nvidia GPU using nvidia-331, SSD

 

Still no solution, but I've at least (hopefully) eliminated some more
variables.

As I know this problem doesn't currently exist on Vivid, I tried back-
porting `network-manager` and `network-manager-applet` from Vivid, but
no luck... same problem still exists.

And on the off chance that this is kernel-related, I also tried the 3.16
kernel on Trusty... but connecting to WiFi still works fine, so it
doesn't seem to have anything to do with the kernel version.

However, I have noticed some differences in the Dbus processes running
an a system with Nvidia hardware vs a system with an Intel GPU, so I'm
further investigating that today...

Also, I'm not that familiar with network-manager, so if you have any
advice for how I could get you better debugging information, please let
me 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.
