[Nouveau] NV43 (6600 Go) Report

[Pascal Schoenhardt]

OK, so I have compiled and installed the randr1.2 branch of nouveau.
The problem I am having is the following: with just the laptop
flatpanel display connected, x won't start; with an external device
connected, x starts but all displays remain blank.

With just the laptop panel on its own, X fails with:
  (EE) NOUVEAU(0): No valid modes.
  (EE) Screen(s) found, but none have a usable configuration.

I have tried the following settings for xorg.conf:
  -Same settings as before (non-randr1.2 version)
  -Removed all "Display" subsections, to let modes be autodetected
  -All monitor options removed, except the identifier
  -No modes in "Display" subsection, just one large virtual, big
enough to span all my display devices

None of these have helped. Here is a full log output, with non-nouveau
stuff stripped out:

Fatal server error:
no screens found

=========================

Now, when I connect another screen, X actually starts. Reading the log
files, nouveau is getting the EDID info from the external screen
(1024x768 at 70 LCD), and determining the correct modeline (after quite a
lot of probing). As for the internal panel, it seems not to provide
any EDID info. However, nouveau does seem to want to choose 1680x1050,
provided I have specified a virtual large enough to fit that and the
external screen in the xorg.conf (2704x1050).

Once X is started, both monitors are black. However, I can hear the
"please enter your loging credentials" tone you get with ubuntu, and I
can blindly log in to a normal session.

I am guessing that this is just because this branch of nouvea is even
more experimental than the whole project is, so there probably isn't
much to do but wait for it to improve. However, hopefully this is
useful information to some of the devs. And if someone has a tip on
getting this to work, I'm all ears.

Here is a full log of X starting, using a modeline for the internal
panel, defining a virtual screen large enough for the two displays,
and with the external display connected and turned on. This is too
large to post as text, so here's a link:
