Bug 75013

I see that you're using displayport. Is it an actual DP monitor, or are you using a DP->xyz adapter?

I recently posted a patch that should fix computing number of lanes/lane speeds for DP on pre-nvd0 cards: http://lists.freedesktop.org/archives/nouveau/2014-February/016205.html

Can you see if that helps you? Should apply to any 3.9+ kernel.

Some highlights from the logs
* Dual gpu system - intel + nouveau combo
* Default GPU: intel(Haswell Desktop?), ddx version 2.99.904
* nouveau ddx version 1.0.9
* Mesa 9.2.1
* The following Xorg.log spam could be related (coming from xserver/randr)

I am not using the Dislay Port. My monitor works only on the VGA(The DVI port is not functional). So I have plugged it to DVI port via DVI->VGA adapter.

I tried the patch but no luck :(

Yeah, if you're not using the DP port, I wouldn't expect it to. In hindsight, I realized that I misread your log -- you're using the DVI-I-1 connector, not DP-1.

Unfortunately I don't have any great ideas atm... could you try to upgrade to the latest kernel and see if things have magically resolved themselves?

Assuming that they haven't, can you attach a boot log with

nouveau.config=PDISP=debug,VBIOS=trace drm.debug=0xe

from the latest kernel? Perhaps it'll yield some interesting info.

I will try that. One observatino is that the issue is not seen with Live CD. Is there a difference between the installed OS and the live CD? This surprised me, as I was expecting a smooth sail...

Depends on the Live CD, doesn't it :) In the Ubuntu case, I haven't the slightest clue. I'm guessing it has different versions of something -- would be good to figure out what versions it's running and what versions you're running on the installed system of:

(a) kernel
(b) xf86-video-nouveau (potentially called xorg-server-video-nouveau or something else along those lines)
(c) libdrm
(d) mesa (specifically the dri drivers)

Those 4 pieces of software basically make up nouveau. I doubt the last 2 really matter for your case, but... no harm done grabbing versions.

I am for the time being giving up. I was unable to build a TOT kernel that would boot. For now, falling back to the onboard graphics card. Will try to post the findings when I get some time. Hope there is resolution for this issue, otherwise I will be left with a 100$ card that I cannot use :)

No update in quite a while, marking invalid. If the issue persists with fresh software, feel free to reopen.
