i have been having a Serious Issue with my LG notebook and its Nvidia Geforce 310M GPU. It usualy (99% of the time) happens when i leave the computer idle for a while, but it has also happened sometimes while i was using the PC. Suddenly, (usualy when computer is idle) the screen goes black, and the pc freezes completely on the black screen. (not even ping responses). The only sollution is to Hard Reset the machine. When analizing the syslog, i see the following error:

Sep 18 20:58:08 yuri-notebook kernel: [ 1936.510073] NVRM: GPU at 0000:01:00.0 has fallen off the bus.
Sep 18 20:58:08 yuri-notebook kernel: [ 1936.510087] NVRM: GPU at 0000:01:00.0 has fallen off the bus.
Sep 18 20:58:08 yuri-notebook kernel: [ 1936.510157] delay: estimated 354, actual 1
Sep 18 20:58:08 yuri-notebook kernel: [ 1936.510173] delay: estimated 353, actual 0

I have already tryed different versions of the Nvidia Drivers, and also tryed removing each of my 2 DDR3 memories. The problem does not seem to be hardware, because when i boot into windows 7, it works normaly, for days.

I am desperate with this problem, because it makes my Ubuntu practicaly unusable.

Thanks in advance,

Can you please add how fast was the bus going. Nvidia might have survived the fall. This is because other video cards are "Envy" of "NVi"dia. – Luis Alvarado Jan 3 '13 at 17:14

Problem solved by removing ALL nvidia drivers, and installing Nouveau drivers. =D

Just so you know, am also having the same problem, but I do not want to use the Nouveau drivers. Will still look for an answer. – Luis Alvarado Jan 4 '13 at 3:14

Great, so now you have no video acceleration and no 3D by falling back to a basic open source driver. This is NOT a solution. This seems to be a serious bug in the recent Proprietary NVIDIA driver.

I found this post by googling and felt compelled to comment so anyone inexperienced is not misled into assuming this is a solution! Submit a bug report with NVIDIA! I will be doing so shortly.

NVRM: loading NVIDIA UNIX x86_64 Kernel Module 304.32 Thu Aug 2 18:41:39 PDT 2012 NVRM: GPU at 0000:01:00.0 has fallen off the bus. NVRM: Xid (0000:01:00): 48, An uncorrectable double bit error (DBE) has been detected on GPU (03 02 01). NVRM: os_pci_init_handle: invalid context! NVRM: os_pci_init_handle: invalid context!

Seems to have been triggered when I ran VirtualBox and went to run a game (which normally works fine)... After about 10 seconds, black screen.. I ssh into the machine from another computer and discover the above...
