Description kirchmeyer 2011-03-02 05:33:45 UTC

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...

Comment 1 Maarten Maathuis 2011-03-02 05:42:28 UTC

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.

Comment 3 Ilia Mirkin 2013-08-18 18:09:53 UTC

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
