           Summary: DVI Dock Connectors: Signal but not usable.
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: kirchmeyer-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org
         QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org


When monitor(s) plugged into DVI port(s) (any combination), the monitor stays
black as if it has a signal (no check cable message) however they are not
available to use. xrandr does not report any DVI ports. Please let me know what
further information would be useful.

VGA seems to work...

[Bug 34919] DVI Dock Connectors: Signal but not usable.

The reason is:

[drm] nouveau 0000:01:00.0: Off-chip encoder 6/0 unsupported
[drm] nouveau 0000:01:00.0: Off-chip encoder 2/0 unsupported
[drm] nouveau 0000:01:00.0: Off-chip encoder 6/1 unsupported
[drm] nouveau 0000:01:00.0: Off-chip encoder 2/1 unsupported

No idea how much work it is to implement support.

Ok well at least I know it's not something I'm doing wrong. Honestly this is
the only reason that keeps me from sticking with nouveau.

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
