Title:
  nvidia-current fails to install kernel module after upgrade

Status in “nvidia-graphics-drivers” package in Ubuntu:
  Incomplete

Bug description:
  I have Ubuntu 12.04.2 LTS, and have two Nvida Quadro NVS 295 graphics
  cards, with three Apple Cinema displays.

  I've enabled unattended-upgrades, and this morning I rebooted my
  machine.  After the reboot, only one monitor was working.

  According to the /var/log/Xorg.0.log file, the kernel module was
  absent:

  [   489.570] (II) LoadModule: "nvidia"
  [   489.570] (II) Loading 
/usr/lib/x86_64-linux-gnu/xorg/extra-modules/nvidia_drv.so
  [   489.570] (II) Module nvidia: vendor="NVIDIA Corporation"
  [   489.570]    compiled for 4.0.2, module version = 1.0.0
  [   489.570]    Module class: X.Org Video Driver
  [   489.574] (EE) NVIDIA: Failed to load the NVIDIA kernel module. Please 
check your
  [   489.574] (EE) NVIDIA:     system's kernel log for additional error 
messages.
  [   489.574] (II) UnloadModule: "nvidia"
  [   489.574] (II) Unloading nvidia
  [   489.574] (EE) Failed to load module "nvidia" (module-specific error, 0)

  According to lsmod, there is no such module installed; modinfo and
  modprobe both report module not found.

  After much trial and error with google, the solution was to do the following:
    1. run jockey-gtk
       Note: none of the proprietary drivers were enabled in Jockey's list of 
drivers.
    2. Select the first one 'NVIDIA accelerated graphics driver (version 
current) [Recommended]'
    3. Click on 'activate'
       This procedure took a while and eventually hung.
  Viewing the /var/log/jockey.log seemed to indicate the procedure had failed.
    4. run 'modinfo nvidia_current'
        I really didn't expect this to work, but it did!
    5. run 'modprobe nvidia_current'
    6. restart X

  I haven't tried rebooting yet, as I wanted to report the information
  while it was still fresh in my mind.

  I'm not sure what package this bug should be assigned to: jockey?
  nvidia-current?  unattended-upgrade?  other?
