Title:
  NVIDIA graphics performance significantly decreases after upgrading to
  3.13.0-1

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Graphics driver: nvidia-331-updates (Version: 331.20-0ubuntu9)

  My Quadro 1000M card worked well on kernel 3.11 or 3.12 from the
  official repo. But after upgrading to 3.13.0-1, significant lag can be
  perceived. I downloaded and use the old 3.11 kernel from saucy repo
  again. Then performance is OK, so it's not the driver's problem.

  All packages are installed from trusty repo, no PPA is used. And I have never installed or compiled softwares manually.
