dmesg run from ssh

Hi,
my card is unfortunately useless with nouveau
when I bootup a "corrupted" screen shows up
and stay there, after everything is loaded
and X is supposed to start it doesn't start
so either X and console doesn't work with it.

I'm using xorg-edgers drivers from ubuntu PPA,
that use to be quite new, just in case a fedora
live cd also doesn't boot.

Please ask if so can provide more info

Thanks.

Two things, it's an NVA3, not NV40.

Secondly i notice the word "Optimus" in your log, which to the best of
knowledge means that you have a mixed intel/nvidia system and the nvidia gpu
doesn't have any outputs/monitors attached, only the intel.

As far as i know optimus is not (well) supported under linux, but others might
know more about that.

In the meantime, the intel driver in principle should work (although the nvidia
gpu may still be consuming energy and doing nothing) if this is really an
optimus system.

That optimus message is a mistake that is fixed in newer kernels:

commit f24f9104f70cabc2534b16f94149d33127d249d5
Author: Dave Airlie <airlied at redhat.com>
Date:   Wed May 2 20:26:24 2012 +0100

    nouveau: initialise has_optimus variable.

    commit addde4ec31456c5f1e9b61aae3edcfeb0f338f87 upstream.

    We should initialise this to 0 really to avoid getting false positives.

Ok I didn't know it was NVA3.

And as the last comment says it's a mistake message,
since I run a desktop with an off board PCI-E card.

Is it possible that a newer kernel don't think I have
an intel? Or there might be another issue not
related to this?

Thanks.

I have some news, I belive the commit shown here
actually disabled this optimus feature that is not
really available here, so using a kernel 3.4-rc6
shows kubuntu logo at 1920.1080 and allows me to
use the console, however the X still doesn't start.
Since I got a kernel patch upstream I did the test
to see if it was working fine and ended up noticing
nouveau starting to work here...

I'm adding a new dmesg log
