Bank screen after resume on Dell XPS M1330

I am struggling with new pet. One of the issues is that resume seems to 
work but display is blank. I can blindly enter commands (e.g. to cleanly 
reboot) so system is perfectly alive - just no output on LCD.

This happens on both 2.6.29 and 2.6.30-rc4 in both 32 and 64 bit 
kernels. Also it happens using init=/bin/sh which at least rules out any 
video driver issue.

lspci follows just in case. I am open for any patches and suggestions :)

We don't know how to reinitialise nvidia graphics hardware.

Just in case - same issue also after resume from hibernation. I was 
under impression, that hibernation does not have these issues as card 
goes via normal POST routine.

Hmm ... this implies users of nVidia are locked to proprietary driver if 
suspend is required?

Hm. That sounds a bit weirder.

s2ram tool and/or Xserver may be able to reinit the video....

Ok, that's bad. There still should be chance to reverse-engineer the
BIOS or tweak the emulation in libx86 until it works with the nvidias,
but... that's a lot of work.

nvidia BIOSes call into chunks of system BIOS code that aren't available 
after boot. They rewrite themselves so the c000:0003 entry point just 
returns in order to prevent you from executing random code. It's not an 
emulation issue. The only way to fix this is to finish nouveau's 
implementation of the nvidia bios table bytecode and execute the init 
tables on resume.

Is it worth further debugging? Anything I can provide?

Try it with minimum config, init=/bin/bash? Switch to plain vga
console?

As stated in my first mail, that is exactly what I started with :)

Ok, ok, and even that failed with hibernation?

You are right, I was not careful when testing. I tested once more with 
two different kernels; hibernation works (also in normal init 3) as long 
as video settings are the same between suspend and resume. If they 
differ (e.g. plain VGA before suspend and frame buffer after) display is 
most likely completely garbled (but still is not blank).

Of course, any attempt to switch to X (using nv driver) after resume is 
doomed. OTOH *starting* X after resume seems to work. 

Sorry for the noise.

Ok, that's what I'd expect. Hibernation _should_ work on any hardware.

Now, nv driver probably has a problem that needs to be fixed... You
should be able to use framebuffer X driver and have hibernation
totally working for you...

And no, different video modes between hibernation and resume are bad
idea.
