Hi,

I tested Nouveau with 2.6.34, and now with 2.6.35-rc2 and It does not work 
with my laptop (chip NVIDIA GeForce 330M GT). (I give more information of the 
nvidia chip below). I've seen an error message related to my nvidia chip that 
may also be related to my problem :

pci 0000:01:00.0: no compatible bridge window for [mem 0xfff80000-0xffffffff pref]

Thanks in advance for your response.

Best regards

	Eric

Here more information :

This is not enough information. Most of the useful information is
prefixed with [drm], but generally a full log from boot to fail is

Please make sure nvidiafb is not loaded. If you still have issues
after making sure that nouveau is the only kernel module running for
this device please attach a full log.

nvidiafb is not loaded.

I've attached the full log. And here are the drm lines of the log :

Is this a system with switchable graphics (Optimus probably)?  If so,
fiddle with your BIOS options and try and enable only the NVIDIA board.

Dave has some patches that can retrieve the VBIOS image via ACPI which
may be of use to you, but I'm not sure of the status.

oops, my fault... I forgot to switch to the nvidia chip (my laptop is a sony 
vaio Z11Z9E) with the button. Here the new drm logs with a 2.6.35-rc2 kernel :

Aah, yep, that's much better.  I've seen what I believe to be a similar
issue reported, but other things have prevented me looking at it
properly yet.

I'm on holidays for the next 2 weeks, but I'll get back to looking at it
then.  The only suggestion so far is to make sure you're using the very
latest code from nouveau git, just to make sure it's not already
fixed :)

Ben.
