[Bug 1529360] [NEW] lubuntu 14-04 xorg server crash every 6 hours nvidia

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

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
