dmesg|grep "nouveau|drm"

My HP Pavilion dv9560eg sports a 8600M GS video chip with a design defect (for
the interested: http://www.scribd.com/doc/19308567/Nvidia-Class-Action).

Good thing is, under certain circumstances it may still be used.

1. Sometimes it boots up just normally and works for a certain time (hour or
so).
2. If #1 fails I have to set "nomodeset" to actually see something,
otherwise (when the mode gets set) the screen get white and fades to grey in an
awkward
way. I can still blindly login  or use ssh.

With "nomodeset" only the first line, otherwise all of those lines can
be found in dmesg.

Unfortunately I haven't logged dmesg output in the few moments the machine
boots up normally.

I'm using "xserver-xorg-video-nouveau
1:0.0.16+git20110823.169512fb-0ubuntu0sarvatt~natty" on Ubuntu 11.10 with
kernel 3.3.0-030300rc3-generic-pae.

Hi Chatty

If I have to be honest I'm surprised it works at all (considering the issues
nvidia had with those cards)

* Can you please confirm if the blob (proprietary driver) works fine with your
card

After a quick look I've noticed that

* Nouveau is using the vbios fetched from the PCIROM
* The vbios does not appear to be correct

As a workaround can you try appending the following to your kernel command line

nouveau.vbios="pramin"


It will tell nouveau to use the PRAMIN vbios, thus possibly resolving some of
your problems

Note - I seriously believe that there is a hardware problem with your card
considering the hardware issues that have been noticed (and confirmed in the
linked
document)

Hi Emil,

the blob fails at "could not load nvidia kernel module", unfortunately
dmesg doesn't show anything about that. Again, I know the card is damaged
somehow (had
it repaired a few times, but problems reoccur always). But odd thing is, it
still works in VESA mode - only 1024x768, but it works.

When using your kernel parameter it dmesg stops here:
[   16.190148] [drm] Initialized drm 1.1.0 20060810
[   17.009568] nouveau 0000:01:00.0: power state changed by ACPI to D0
[   17.009574] nouveau 0000:01:00.0: power state changed by ACPI to D0
[   17.011184] [drm] nouveau 0000:01:00.0: Detected an NV50 generation card
(0x086500a2)
[   17.015638] [drm] nouveau 0000:01:00.0: Attempting to load BIOS image from
PRAMIN
[   17.104300] [drm] nouveau 0000:01:00.0: ... BIOS checksum invalid
[   17.104304] [drm] nouveau 0000:01:00.0: No known BIOS signature found

Once there was Video BIOS update from HP which came as PC BIOS update which
supports the assumption PCIROM BIOS is correct. But due to the hw failure the
VBIOS
does not get copied into the right location. I guess if it could be supplied
from file it might work a treat.

Latest BIOS is in here: http://ftp.hp.com/pub/softpaq/sp48001-48500/sp48024.exe

Btw, Windows 7 VESA driver is able to switch to 1440x900 (native display
resolution) - NVidia driver fails to load as well.

Had a colleague of mine with similar issue - repairing the card/gpu only fixes
temporary

Considering this fact and that the blob does not even run (Linux nor Windows),
I would recommend getting a new card/laptop

Closing as invalid
