[Launchpad Bug Tracker <1307069@xxxxxxxxxxxxxxxxxx>]

This bug was fixed in the package ubuntu-drivers-common - 1:0.4.14

---------------
ubuntu-drivers-common (1:0.4.14) xenial; urgency=medium

  * gpu-manager.{c|py}:
    - Rely on udev for card detection. This helps detecting if a module
      was unloaded or if a card was disabled on a hybrid system.
      In addition to being more accurate (LP: #1485236), this should also
      be much faster on boot (LP: #1307069).
    - Restrict the search for built modules to the dkms directory. This
      improves performance.
  * debian/rules, setup.py, 71-u-d-c-gpu-detection.rules,
    u-d-c-print-pci-ids:
    - Provide a udev rule to detect cards and modules.
