Nouveau - Mar 2011 - [Bug 35475] New: asus laptop boots to blank screen 2 out of 3 times

https://bugs.freedesktop.org/show_bug.cgi?id=35475

           Summary: asus laptop boots to blank screen 2 out of 3 times
           Product: xorg
           Version: 7.6
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: high
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: marius.melzer at rasumi.net
         QAContact: xorg-team at lists.x.org


System: Asus Pro36 or U36, "Nvidia Optimus" hybrid graphics with a gpu
in the
core i5 processor and a dedicated nvidia geforce 310m graphics card.

Software: Next Ubuntu Release (11.04; Natty) with Xorg 7.6, nouveau ddx driver
1:0.0.16+git20110107+b795ca6e-0ubuntu6, libdrm-nouveau1a 2.4.23-1ubuntu5,
Kernel 2.6.38-7-generic

In 2 out of 3 times, my laptop boots very early to a black screen. When using
"nomodeset" it works fine, so it might be a kms-related problem. The
laptop is
using hybrid graphics. When looking into the dmesg-logs afterwards, I found
out, that when the nouveau-driver initialises normally, the boot fails and if
the nouveau driver fails, the boot works fine.  Yes, this way round! I guess,
when nouveau fails (interestingly with "chipset not supported reason"
that does
not appear the other times), the intel chipset is used.

Dmesg-logs when boot fails:

the dmesg logs are the other way round: the upper one is when it boots and the
other when it doesn't!

This looks like a race between ACPI power-up and nouveau kicking in to detect
your card and additionally to that it seems to choose the wrong chip when
nouveau loads correctly.

Dave, could you please take a look at this? I'm not an expert with optimus.

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
