[Bug 390158] Re: [MSI MS-7329] suspend/resume failure [non-free: nvidia]

[Indie]

I've tried the latest Lucid build and that produces very similar
results. The main thing I notice about it is that it's using the nouveau
driver which is what I think is responsible for what I'm seeing.

Again, I ran the test in single user mode. It wasn't possible to remove
or disable the nouveau driver. Running a pm_trace produces the same
results as before. But seen as it resumes from suspend that's of no use?

When it comes out of suspend, unlike previously, the power light on my
LCD monitor turns green and pops up with the message No Signal. I'm
guessing this is down to the nouveau driver, it's sending the signal to
the monitor to turn back on but it's not turning on the output. My Media
Live system is connected via an HDMI port on the back to a DVI port on
my monitor. Looking at the dmesg output generated by the nouveau driver
it recognises this. A few seconds later the monitor then goes into
automatic suspend, the led turns orange. Everything on it appears to
work correctly, USB keyboard etc.

>From Google I did come across a windows driver "nVIDIA ForceWare 81.98"
and in the change log of bug fixes it mentioned "GeForce 6150/6100,
Windows XP Media Center Edition 2005: The display remains inactive when
resuming from Suspend mode." So I don't know if there's anything special
that needs to be done with this particular chipset to wake it up?

As another test, I tried "vbetool dpms off" which works though when I
try "vbetool dpms on" it doesn't turn the monitor back on. However for
some reason when I did "vbetool vbemode set 283" the monitor turned
itself back on though the screen was messed up - the left handside was
now in the center of the screen and it scrolls off the bottom. I just
thought I'd try something to manually set the resolution in the hope
that it would pop back into life. This though did not have any affect
after a resume from suspend.

The change I've seen, the monitor now turning back on after resume but
still not having a signal, I'd image would be due to the nouveau driver.
Should it not 'work' without this?

I found a post about suspend http://forum-
en.msi.com/index.php?topic=120345.0 ,presumably it's on windows, saying
that it started to work correctly in BIOS 1.63 which is the same version
I'm using. So I'm guessing something's been missed out when the system
resumes from suspend for the display to not wake up.
