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.
