Public bug reported:
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.
