[Bug 993187] Re: ubuntu 12.04 completely freezes frequently.


I have been facing this problem for a long time now and it still doesn't
seem to get fixed. To me it happens most often on multimonitor using
HDMI, but also with a single monitor or multimonitor using VGA.

Using a Dell Studio XPS 1340 laptop with:
Ubuntu 12.04
Kernel: Linux 3.2.0-57-generic x86_64 GNU/Linux
CPU: Intel(R) Core(TM)2 Duo CPU     P8700  @ 2.53GHz
nvidia-smi -L
GPU 0: GeForce G210M (UUID: GPU-1b0674e3-9c44-6152-8b35-14ac258e89df)
GPU 1: GeForce 9400M G (UUID: GPU-0c72438f-4b81-5d92-cf00-974a003c6fc5)
Driver Version: NVIDIA-Linux-x86_64-331.20 - dowloaded from NVIDIA site, but getting the same problem with the ones in the Ubuntu repository

I've been losing a lot of time trying to fix it by reinstalling NVIDIA
drivers. It caused me to lose a lot of work by freezing my computer

Bug description:
  Update: 6/12/2012
  This bug is about a complete system lock-up. No other TTYs can be started. Mouse doesn't move. Keyboard doesn't react. The only solution is hard reset.

  Seems to happen on a variety of configurations, including nVidia, ATI
  and Intel graphics.

  If you are still able to TTY or SSH into other sessions, move the
  mouse or use the keyboard, file another bug.

  Thx. Joris V. (brains).

  Update: 5/21/2012
  Updating the kernel to 3.3.6 as suggested by Michael in #91, the system seems stable, no freezes yet in 5-6 hrs of using and watching videos for couple of hrs.

  Original description:
  I recently installed newly released ubuntu 12.04 LTS 64 bit version on my desktop. And it is frequently freezing, for the first few hours it ran smoothly and when I started watching videos it started freezing randomly.
  I have to use hard restart every time.
  Initially it was only during videos but now even during normal browsing it is freezing.

  I am using on board graphics and do not have any graphics card

  Can someone please help me here, I really love the new looks of 12.04
  and it bugs me not being able to use :(

  Below is my hardware configuration:
  Processor: Intel CORE i3 processor (2nd generation)
  Board: Intel® Desktop Board DH67BL
  Ram: 4GB
  Graphics: On board
  HDD: 500 GB

  Please let me know if you need more information, or any specific logs
  I can capture (and how).
