Nouveau - Oct 2010 - [Bug 31026] New: External display does not work with Nouveau driver

https://bugs.freedesktop.org/show_bug.cgi?id=31026

           Summary: External display does not work with Nouveau driver
           Product: xorg
           Version: 7.5
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: lcid-fire at gmx.net
         QAContact: xorg-team at lists.x.org


I switched from Nvidia to Nouveau driver and I have to say you guys did an
amazing job. Thanks a lot. One gripe (aside from slow 3D performance) I have is
that it doesn't access the external monitor of that machine. I can enable
the
external one but it doesn't even recognize that it does get any signal (led
does just blink).

I'm going to need a lot more info than you've provided to have any clue
about
this one.  You don't even say *what* card you have!

Can you attach your dmesg output while running the nouveau driver, preferably
from after you've tried to attach the external display also.

Thanks.

Xorg log

Don't know why Bugzilla didn't attach the log when I created the bug.
Buggy
software.

I *think* your problem is probably fixed in nouveau git.  It looks like the
kernel you're using has a version of nouveau with a display-related
regression,
that has been fixed for a long time now.

Indeed - I upgraded to 2.6.36 and it's fixed there. Thanks
