 Title:
   Kernel Bug - 11.04 through 12.04 - Concerning Multiple GPU graphics
   cards

 Status in "linux" package in Ubuntu:
   New

 Bug description:
   I've tried to get my GTX 295 to work on multiple versions of Ubuntu,
   but this has failed.  I know that the card itself works.  I contacted
   NVidia and they said that it was most likely a kernel bug.  I tried
   12.04 off of a liveCD and that wasn't any different.  I installed the
   proprietary drivers on a persistence file on the live USB, but that
   didn't work either -> That's the set-up that you have the information
   on.

   The issue is that the kernel doesn't seem to detect both GPUs on the
   card properly.  My lspci shows 2 GPUs, but it should show three (I
   currently have a GTX 460 SE and a GTX 295 in the machine, so there
   should be a GTX 460SE entry and two GTX 295 entries.)

   Most lspci methods didn't detect anything else at all, but when I
   used, 'lspci -A intel-conf2', I got, "00:08.0 Non-VGA unclassified
   device: Device aebc:75c5".  Nothing shows up on that address when I
   use the other detection methods and I'm not the expert, but I'm
   guessing that the problem is somewhere in that area.

   So I suppose that the reason that I'm giving you all of this extra
   information is because I don't know what EXACTLY the problem is, but
   it seems that the kernel is unable to decide how to deal with this
   multi-GPU card.
