Title:
  lubuntu 14-04 xorg server crash every 6 hours nvidia

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  Everything is fine (no memory leak) up until a random instant
  (sometimes correlated with watching flash videos, but othertimes just
  plain inactivity triggers it), then all RAM is used up in a matter of
  seconds, mouse become unresponsive and xorg-server logs me out

  I asked a question on askubuntu but didn't get any attention :

  http://askubuntu.com/questions/703936/lubuntu-14-04-xorg-server-crash-
  every-6-hours-nvidia

  Copy pasting it here :

  Every few hours my fresh Lubuntu 14.04 laptop crashes violently.
  Bringing Xorg server down. I have an asus ROG with geforce gtx-960m.

  I looked at the xorg server log and it seems to point to a Nvidia
  crash.

  I had problems with nouveau drivers. So I went to https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia
  And executed

      sudo ubuntu-drivers devices
      == /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
      modalias : pci:v000010DEd0000139Bsv00001043sd0000185Dbc03sc02i00
      vendor : NVIDIA Corporation
      driver : nvidia-352 - distro non-free recommended
      driver : nvidia-352-updates - distro non-free
      driver : xserver-xorg-video-nouveau - distro free builtin

  Then proceeded to install nvidia-352 as recommended via apt-get. It
  works fine except when it crashes every ~6 hours (sudden memory leak
  then freeze) : When running nvidia-settings it says driver version :
  352.63 And I can run cuda and opengl just fine.

  Previously I was under 14.10 then 15.04 and it was working OK until
  the 15.10 migration, which was so unstable I had to install back a
  fresh 14.04.

  What did I do wrong ? Can you advise what I should do ?

  The fix consisting of turning off gpu acceleration helps to stabilize
  a little but it still crash at least once a day.
