When I boot my computer with nouveau and KMS, I get a black screen after UDEV
starts on Debian Testing. I've attached some logs.

Did this ever work? Looks like the internal LVDS screen is detected just fine,
resolutions are all there, no errors. Is it right that the internal screen is
1920x1200?

Can you confirm that the problem still exists with 3.16-rc5?

I will compile and test 3.16-rc5

I've only ever used Nvidia's drivers on this particular computer so far. The
screen is 1920x1200. It is an old Dell XPS 1730.

This is still not working on Kernel 4.2. But during this test I had the laptop
connected to a DVI output. And the DVI output worked great. So it seems this is
not working for the LVDS only, which has the black light on but remains
blank/black.

I noticed on a Google search that there had been blank screen issues on
pre-nv50 drivers: http://patchwork.ozlabs.org/patch/215168/

I wonder if this is something that exists on my card as well. I was glad to see
the display working on the DVI output, but I am hoping to have this working on
LVDS at some point.

Thanks

A random thing to try -- boot with

video=LVDS-2:d

(It appears that you have 2 GPUs... perhaps they're both connected to the LVDS
somehow, and the second one turns it off?)

I tried this. And it was still a black/blank screen. However maybe you are onto
something as this is a laptop with a Nvidia 8700m setup as an sli card. Though
with the proprietary driver and with Windows it has no issue booting up
properly. However I find windows really slow and would like to switch to
nouveau to future proof my laptop since I am betting Nvidia won't develop a
Wayland driver for this card.
