        <pre>This is on Arch Linux. After an update, my 2nd monitor was no longer detected.
I downgraded nouveau to the Arch package version 1.0.15-2 (from 1.0.15-3) and
the problem went away. I also had to downgrade xorg-server due to dependency
issues, so it's possible the problem could be there and not in nouveau itself.
My xorg-server package is now xorg-server-1.19.6+13+gd0d1a694f-2, down from
xorg-server-1.20.0-2.

Both monitors work fine in the downgraded configuration, but only one works
with the latest updates.

When things weren't working, /var/log/Xorg.0.log showed the message "failed to
find screen to remove" for one of the GPUs. This is no longer the case after
the downgrade.</pre>
