Actually, I tried a few more times, in order to get the right EDID, but then it
seemed to work, except that the screen is all black.

Hi Felipe

Is the monitor connected to the card at boot ?

Can you give it a try and attach your logs as recommended [1]

Thanks Felipe for the logs

It would have been great if you could tell us if the DP monitor is working at
boot, and at what exact moment it switches off - i.e. load of radeon/nouveau

Looking at your logs it appears that you have a laptop with two cards/gpus

Have you looked at Optimus [1]?

Does this setup work with the proprietary driver ?

For some reason Xorg.log is saying that you have 2 monitors connected to your
laptop, apart from the LVDS

AFAIK nouveau/nvidia cannot control more than two outputs, thus can you try
only one at a time ?

Cheers

No, it doesn't work at boot, and it never switches off. The led turns blue, as
if it just received signal, but it stays black. The back-light is on and
everything, there's just nothing there.

> Looking at your logs it appears that you have a laptop with two cards/gpus

Nope.

What is that?

Yes.

I do.

I'll try, but my LVDS is broken, so it would be tricky.

Nope, same thing, even when I removed my VGA output display and rebooted.

By bad forgot the Optimus link [1]

Whereas for the two GPU/cards I got this from your dmesg


[    0.807677] [drm] radeon defaulting to kernel modesetting.
[    0.807678] [drm] radeon kernel modesetting enabled.

[    2.144701] [drm] nouveau 0000:01:00.0: Detected an NV50 generation card
(0x0a5e00a2)

Can you attach the output of lspci just to confirm/dismiss the above


You can try the following 
1. Append "video=LVDS-1:d" to your kernel command line to disable the LVDS
2. Choose a lower resolution for your DP monitor - "video=DP-1:1024x768@60"

Cheers

That's probably because CONFIG_DRM_RADEON=y (I compile my own kernel), but
shouldn't affect anything; the driver just doesn't detect anything. Now I've
compiled it as a module, and still no change.

Where does your nouveau kernel module come from?  The code in nouveau kernel
git should support native DP outputs correctly now, if you're not already using
that code, it's worth a try.

What do you mean by "git"? 3.1-rc5?

Indeed, I tested that code and it's working fine.

Now I wonder when it will be merged to Linux upstream... I guess 3.2, right?
