Nouveau - Aug 2010 - [Bug 29766] New: suspend-to-ram problem on GF7600 notebook

https://bugs.freedesktop.org/show_bug.cgi?id=29766

           Summary: suspend-to-ram problem on GF7600 notebook
           Product: xorg
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: mjt at tls.msk.ru
         QAContact: xorg-team at lists.x.org


I've sent this bugreport to the mailinglist, but apparently the post
produced
no interest whatsoever.  So re-submitting it here.

Full details are at
http://lists.freedesktop.org/archives/nouveau/2010-August/006238.html , dmesg
from the bootup are here:
http://lists.freedesktop.org/archives/nouveau/attachments/20100817/bc561c8f/attachment-0001.asc
.

In summary, current KMS driver in kernel does not work in suspend-to-ram-resume
cycle, leaving the screen non-functional after resume, at least on a particular
notebook, and generating tons of kernel messages.  There's no X involved at
all
(I tried to suspend/resume without starting X), but from X the behavour is the
same.

I selected x86(IA32) arch, but exactly the same happens with 64bit kernel.

Thanks!

I have the same problem on with my GeForce 7600 GT PCIE card on my desktop. If
in console, fonts become  upon resume. If using X, I get a hard crash and
garbled black and white lines upon resume.

This problem still exists with current 2.6.38 kernel.  Here's some more
information about it.

The most important part is that the notebook can suspend+resume just fine (and
fast!) when _external_ monitor is connected to its VGA output.  The only
annoyance in this case (besides the whole fact that it needs external monitor
to function properly) is that only external monitor shows anything at all up
until the nouveau driver is loaded or when it finishes the resume-from-disk
cycle.  So it appears that the whole thing works with external VGA attached.

When only internal (LVDS) panel is connected, the machine never resumes
correctly: it works, it's visible from the network, all processes are
working,
but the screen stays blank, even after re-connecting the external monitor.

Attached are two dmesgs with 2.6.38 kernel from bootup.  First,
dmesg-2.6.32-good-extvga, shows 2 successful suspend-resume (ram) cycles with
external monitor connected.  Another, dmesg-bad-noextvga, shows one
unsuccessful attempt to suspend-resume it, with quite some errors/warnings from
nouveau driver at the end.

It appears that this bug report has laid dormant for quite a while. Sorry we
haven't gotten to it. Since we fix bugs all the time, chances are pretty
good
that your issue has been fixed with the latest software. Please give it a shot.
(Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git
versions.) If upgrading to the latest isn't an option for you, your
distro's
bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs
that haven't seen updates since 2011. If the original issue remains, please
make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/
for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
